Mexican Sunflower-Butterfly Favorite

If anyone ever asks me what flower draws the most butterflies to my garden, I don’t hesitate to say- Mexican Sunflower. Tithonia rotundifolia ‘Torch’,  attracts beneficial insects such as hover flies and minute pirate bugs, and of course- butterflies. This coarse textured plant grows up to seven feet high in my veggie garden and meadow and is sure to draw all the butterflies around, especially Monarchs. Better than sunflowers which flowers for a short period, Tithonia bears dozens of flowers at a time and lasts all summer.

If you are Monarch watching, you must plant at least one of these handsome plants. Hoards of monarchs will visit while it is blooming for at least 3 months solid.

Butterfly on tithonia

Easily grown from seed sown outside after frost stops, the plants shoot up quickly to tower over everything surrounding it, so I make sure to place a rebar stake next to it when it gets a few feet high. Rebar or another sturdy stake is needed as the plant can be quite heavy, laden with all those beautiful flowers. Loving heat and sun, be sure to plant them in full sun or just a little bit of shade,  or the plant will not bloom as well and will get rangy looking.

The felted leaves are ruffled on the edges

Drought tolerant, even hating too much water, these plants are so easily grown, that I am always surprised more people don’t grow them. Yes, they can get quite tall (7 feet), but there is a new variety, called ‘Goldfinger’ that only gets four feet tall and I am growing it this summer for the first time to see if I like it as much. I am wondering if it blossoms so profusely as the tall one? Descriptions say it will, but I hold judgement until I grow and experience it.

The blossoms are about 4 inches across 

The flowers are held high above the foliage with the center quite open and accessible for butterflies, and that is why they flock to it. Bees and other pollinators love it also, but especially the butterflies. Check out my post on ‘Butterflying‘  or ‘Plant These For Bees’ for more information on attracting these beautiful pollinators to your garden.

The dried flower centers are also attractive and Goldfinches pick out the seeds

Since the plants grow so tall, be sure to stake it. If you don’t, the first wind storm you have, the plant will break and fall to the ground.

Since one plant can take up a good bit of room, I plant it in my veggie garden

Why You should Grow Tithonia

  • Long bloom period
  • Tall plants make it easy to see and photograph
  • Attracts flocks of migrating Monarchs
  • Easy to start from seed
  • No serious pest or disease issues
  • Attracts a wide variety of pollinators

Hairy Balls Milkweed

I love arranging with “Hairy Balls” for a unique centerpiece
Hairy Balls starting to form tennis ball size  pods

Visitors looking over my garden in the fall, always ask what the strange-looking plant is that is forming large hairy pods. Growing in my veggie garden, because of the amount of space the plants take, my Gymnocarpus physocarpa, or “Hairy Balls” are a conversation starter. A Milkweed family member, another common name is Balloon Plant. Native to South Africa, this plant is an invasive in tropical climates, but in my zone 6-7 area, winter cold keep it in check.

Hairy Balls in full glory

Here are some facts about this amazing plant:

  • Fast growing annual Milkweed, hardy in zones 8-10
  • Can sustain lots of munching monarch caterpillars late season
  • Nectar source for monarch butterflies
  • Long stems with pods make beautiful table centerpiece
  • Last viable Milkweed species before fall frost
  • Start seeds at least 6-8 weeks inside; easy to germinate in about a week
  • Flowers aren’t super showy, but still attractive
  • Fewer pollinators use this than native Milkweed
  • Pinch back the plant to make it bushier and with a stronger stem
  • Place in the rear of a border as it can top off at 6 feet and may require staking
  • The pods become ripe when they turn a tan color and burst open with the fuzzy seeds
  • I save some seeds for planting in early spring in my greenhouse
The single flowers are pendulous instead of a large ball of flowers in the common Milkweed

Though some people have told me that monarch caterpillars have ignored their Hairy Balls, I found at least a dozen of them on my plants at once.

You can see the white substance on the pod at the bottom which is why these plants are called Milkweed

When all of my common Milkweeds are done,  Hairy Balls Milkweed is going gangbusters into October and ending with our first hard frost. I have had these plants look good up to Halloween with active caterpillars.

The ripe balls turn tan and burst open with seeds

Starting these seeds in my greenhouse in early March is essential to Hairy Balls producing the balloon shaped pods by the end of the summer. For most of the summer, these plants grow up and branch out and then August/September hits and the pods start to appear after a flush of small dangling flowers.

The flowers are not showy
The nondescript flowers start forming pods in September
Split a hairy Ball open and you will find hundreds of seeds

For my monarch populations, this Milkweed is important as it still is standing with plenty of foliage late into the summer/early fall. My other common Milkweeds are totally denuded and finished when Hairy Balls hits its stride. For my post on other milkweeds, go to Got Milk….Weed? and Plant Milkweed for Monarchs. 

Common Milkweed has very different flowers and pods
Common Milkweed have long narrow pods

Starting From Seed

I start my Hairy Balls from seed inside around mid-March to get a head start. The plants take a long time to form their wonderful seed capsules and I usually harvest from August on as they form.

To plant, I separate the brown seeds from the fuzzy fibers

Plant the seeds in good potting medium and cover about 1/4″ deep and the plants emerge in about 10 days. I keep them in the greenhouse until they reach about 4-5 inches high and the weather is warm enough- about the same time as tomatoes.

Hairy Ball seedlings about a month old: they need a few more weeks before setting out

Once they are growing well in the garden, I usually pinch them to make them a little bit fuller and bushier. But if you don’t do this step, they still will grow fine.

The plants of Hairy Balls Milkweed get about 4-5 feet tall

Creating a Bumblebee Habitat

Bumblebees Are Important Pollinators

Bumblebees are extremely important pollinators for agriculture both in the field and in greenhouses. Unlike honey bees, they are able to forage under cold, rainy, and cloudy conditions, so it is possible to see them in all kinds of weather. Even on an early chilly morning, you can see a bumblebee sleeping inside a flower blossom, waiting for some warmth to arrive.

The crops that bumblebees can pollinate include tomatoes,peppers, raspberries, blueberries, chives, cucumbers,apples, strawberries, alfalfa, blackberries, soybeans,sunflowers, beans, cherries, apricots, plums, almonds,nectarines, peaches, rosehips, eggplants, and cranberries.

Bumblebee on flower

Bumblebees are also extremely important pollinators of many flowering plants and are generalists, which means they pollinate by visiting hundreds of flowering plants.

Bumblebee Declines
There is evidence that in North America some of our bumblebee species are declining and a few are threatened with extinction. Species that seem most  vulnerable are those with smaller climate tolerances, those at the edge of their climatic niches, and later emerging species. Many species in North America and around the world, are declining at a rapid rate.

Threats

Most bumblebees nest in underground nest, or old logs or crevices. You can help the bumblebees come to your property and nest by providing a ready to move in nest, just as you would to mason bees.

I have mason home plans at Home Sweet Home for Mason Bees.

A ready to move in mason bee house
A ready to move in mason bee house

Ground Nesting

Since most bumbles nest in the ground or a dry, dark cavity, you can provide a simple ground nest with a clay pot, a saucer, some straw, piece of chicken wire, and a short piece of garden hose for an entrance. The low-flying zig zag flight of a nest-site searching queen can be seen in the spring and is very distinctive.

A mature nest of a bumblebee can contain up to 400 residents, as compared to 50,000 to 80,000 honeybees, so the nest is quite small. It should be located in the shade in a dry location. The straw used preferably should be obtained from a mouse’s nest, as a queen will be attracted to the smell. For complete instructions and diagrams, go to Hartley Botanic.

Bee Catnip-Mountain Mint

Bringing bugs into the garden is the new norm, not spraying with insecticides every insect that alights on a leaf. A sea change in how gardeners operate is in motion and most gardeners are embracing it with gusto. Seeing the Monarch numbers plummet recently has brought home the importance of home gardeners taking charge and embracing this change for the better.

Wildlife Value

Not all plants are equal in their ability to support pollinators with nectar and pollen. Penn State has conducted a series of trials on different pollinator plants that evaluated plants for their numbers of insect visitation as well as for their vigor and blooming. Go to their site at Penn State trials to check it out. Not only the number of insect visitors is important, but also the diversity.

I will be profiling a series of plants in the next year that are really important to pollinators- be it honeybee, native bee, hummingbird, beetles, butterflies, or flies. Top of the list is a little-known mint, called Mountain Mint which blooms for 15 to 16 weeks.

Early growth of Mountain Mint in the spring

According to Penn State trials, overall, the single best plant in both 2012 and 2013 and 2014 for attracting both pollinators and total insects was Mountain Mint (Pycnanthemum muticum). A 30-inch-tall, wood’s-edge native perennial with grayish-green leaves and pale-pink summer flower clusters, it is hardy in zones 4 to 8. Originally discovered in Pennsylvania in 1790, this plant increasingly is being rediscovered by savvy gardeners and added to landscapes.

Uses

Mountain Mint is both edible and medicinal. Raw or cooked, the flower buds and leaves are edible and have a hot, spicy, mint-like flavor that makes a great spice or seasoning for meat.

An aromatic herb used in potpourri and as a bath additive, Mountain Mint will freshen laundry in the dryer. Thrown into a drawer, it will keep clothes fresh and moths away. Said to be a good natural insecticide, the dried plant repels insects but the growing plant attracts them! Containing pulegone, the same insect repellent found in pennyroyal, it repels mosquitoes when rubbed into the skin.

Mountain Mint positively dances with all the pollinators that are attracted to it.

How To Grow

Mountain Mint grows up to 2 to 3 ft. tall, usually branched on the upper half, growing from slender rhizomes (underground stems) usually in clusters. The lance -shaped leaves are 1-2 inches long and light green turning to almost white as the plant matures. Blooming in late summer to early fall, flat clustered flowers top the plant with 1/2 inch long pale lavender blooms. Gather tops and leaves when flowers bloom and dry for later herb use.

Not attractive to deer, Mountain Mint will also grow in tough dry shade conditions. Being a typical mint member, this mint travels! So, place it in an out-of-the-way place that it can run free.

Mountain Mint is one of the best nectar sources for native butterflies, and is a nectar filled landing pad for all pollinators.

Many good nurseries will carry this plant. Locally, you can find it at Heartwood Nursery , a great native plant nursery in Stewartstown, Pennsylvania. I found the plants on-line at The Monticello Shop in Charlottesville, Virginia, and even on Etsy and Ebay.

Got Milk…….. Weed?

Common Milkweed

One of the most beautiful flowers, both in flower and seed pod, as well as great importance to wildlife, has been relegated to the roadside for years and virtually ignored. Asclepias syriaca, or common milkweed, is struggling and harder to find because wild areas are disappearing and roadsides are  regularly mown. “Familiarity breeds contempt” is a common saying and one that I would apply to this plant. Only when something becomes scarce do we appreciate it, and I can see that happening with milkweed. But there is a sea change coming down the pike and people are being urged to plant this “weed”.

Colony of Milkweed

Acknowledged as a primary source for survival of many insects, notably the Monarch,  people are waking up to its integral role in supporting other wildlife. See my post Monarch Waystation on the many reasons to plant milkweed for Monarch survival.

Milkweed Facts

  • Milkweed is the only plant on which monarch butterflies will lay their eggs, and it is the only food source for monarch caterpillars
  • It grows in colonies that expand in size every year; each individual in a colony is one side shoot of a large plant and are genetically identical or a clone; one large branching underground rhizome connects the entire colony
Monarch caterpillar munching on a milkweed
  • Surprisingly, the flowers are extremely fragrant and you can smell a colony long before you see it
  • Although one shoot may have between 300 to 500 flowers that make up the umbels, only a few of these develop into pods

    Milkweed pods are positioned vertically

     

  • Vegetative and flower growth is rapid, but the pod development is very slow and held on the plant for many weeks
  • The pods are held vertically to the plant and hold many seeds; germination of these seeds is very sparse; milkweed more likely expands by underground rhizomes than from seed
  • The nectar is very high in sugar content, 3% sucrose, and the supply is constantly being renewed over the life of the flower; the flowers produce much more concentrated nectar than the many insects that feed on it could ever remove
  • Milkweed teems with insect life, providing food and micro habitat to hundreds of insect varieties
  • At least 10 species of insects feed exclusively on milkweeds, notably the Monarch butterfly caterpillar
  • The adult Monarch lays its eggs on the leaves of common milkweed, the larvae live on its leaves and milky sap, and the adult Monarchs drink from the flower nectar, although adults will drink from other flowers
  • The latex milky sap from the milkweed is extremely toxic to other wildlife and is concentrated in the tissues of the Monarch which protects it against predators
Milky sap exudes down the stem
  • The adult Monarch migrates south. East of the Mississippi, they fly as far as 4,800 meters to over winter in Mexico, often to the same tree location
  • This relationship between the milkweed plant and the monarch butterfly makes the pairing a symbiosis, where they become one entity instead of two separate organisms. Most importantly, without the presence of the milkweed plant, monarchs would go extinct.

Other Varieties of Milkweed

Asclepias tuberosa, orange-flowered Milkweed below is probably my all time favorite for drawing insects and pollinators to the garden early in the season, around June for me in the mid-Atlantic. A long-lasting cut flower, I scatter it through my borders to brighten up early summer plantings. It comes in an all yellow version called “Hellow Yellow”.

Yellow butterfly Weed "Hello Yellow"

Another milkweed which is a conversation piece oddity is Asclepias physocarpa (changed to Gymnopcarpus Physocarpus, a mouthfull!), or Hairy Balls. Forming puffy seed balls two to three inches in diameter, the orbs are covered with hairs and are quite bizarre looking. Perfect for flower arranging, the cut branches are quite expensive to buy from a florist, but easy to grow. A favored host of the Monarch butterfly, I always try to grow this plant for the odd looking pods. The caterpillars seem to prefer this variety over all others.

Monarch caterpillars cover the Balloon Plant Milkweed

Tropical milkweed, Asclepias curassavica, is commonly seen growing in Florida and has bright red-orange and yellow flowers and is also a great nectar source. The leaves are narrower and the plant produces many more seed pods than the common milkweed.

My three part series on raising Monarchs.

Preparations for Pupating

Prior to pupating, the cats go on “walk-about”, trying to find the perfect spot to make their chrysalis. In the wild, they can travel up to 15 to 20 feet away in their search. Found in some odd places, the chrysalis might be on fences, flower pots, window ledges, benches, bird houses, siding- just about any structure in your yard or house.

Yes, this caterpillar is searching for a spot to pupate
Yes, this caterpillar has  found a place to pupate and is making a silk “button” to hang from

After crawling around the caterpillar finds the perfect spot to form their silken button that attaches to hang in their prepupal “J”, prior to their last molting. The silk comes from the spinneret on the bottom of the head. After shedding its skin for the last time, the caterpillar stabs a stem into the silk pad to hang. This stem extends from its rear end, called the Cremaster. The beautiful gold dots that adorn the chrysalis are not known to have a function.

The cremaster is black and attaches the pupae to the structure
The Cremaster is black and attaches the pupae to the structure. The pupae on the left was just formed and is still soft, the one on the right has hardened

In the "J" position

For the last skin shed, the caterpillar makes it chrysalis and goes through the “pupa dance”, a process that only takes 3 minutes or less.

Relocating a Chrysalis

Sometimes the cats make a chrysalis in a place that isn’t safe, like on the Milkweed branch that they are eating. In a matter of days when the chrysalis completes the cycle, the Milkweed branch is dead and not sturdy enough to hold the chrysalis. Happening several times in my tomato tower, I relocated the chrysalis using some dental floss. Tying the dental floss around the black Cremaster, I relocated the chrysalis to hang at the top of the enclosure.

Tying a knot around the stem or Cremaster and moving the chrysalis to a sturdy structure enabled this chyrsalis to transform

Eclosure

To witness Eclosure, the moments surrounding a butterfly’s emergence from its chrysalis, is magical, no matter how many times you observe it.  The only way to do that is to have the chrysalis in captivity, where you can monitor its progress and not miss the miracle of metamorphosis. It is extremely hard to catch this happening in the wild as once it occurs, it only takes about 3 minutes from start to finish.

 I missed this one happening. But it still was clinging to the chrysalis, so it just occurred minutes ago
I missed this one happening. But it still was clinging to the chrysalis, so it just occurred minutes ago

Eclosure normally occurs in mid-morning. You will notice the chrysalis darken after about nine days (typical of females) or ten days (typical of males), right before the butterfly emerges. Immediately prior to this, the chrysalis darkens to almost black. Bright orange wings begin to show through the chrysalis covering.

For a great image of the Monarch chrysalis as it ages and changes color, go to Spica’s World.  

Eclosure is close when the chrysalis turns transparent

The excitement builds as you watch and wait for the butterfly to emerge. Typically in early-to mid-morning, the chrysalis’s transparent skin cracks around the head at the bottom. The butterfly pushes it open and drops its abdomen down, still clinging with its legs to the empty shell.

 

When the butterfly first emerges from the chrysalis, it has stubby little wings and a plump body. Fluid from the body pumps into the wings, expanding them to full size in a few minutes. After the wings have fully expanded, the butterfly discharges waste products that have built up during its dormant period. A couple of hours later the wings are dry enough for the butterfly to take its first flight, usually a short one to the nearest tree. As a fully grown adult, it is now ready to mate and to spawn a new generation. You can tell the sex at this time very easily.

Releasing the butterflies is always bittersweet as this generation that comes of age in September is most likely going to make it to California or Mexico for over-wintering. They have a long journey ahead of them. For more information about their journey, go to The Monarch Diaries, Part 1.

Adding fresh Milkweed leaves to the container and cleaning up the gooey frass (poop) is a daily task that only takes a few minutes.

As the cats grow larger, shedding their skins, I transfer them to a slightly bigger container with fresh leaves. Clear salad mix receptacles that you buy at the grocery store make great containers at this stage.

Milkweed-Eat & Grow

When the cats reach about 3/4″ inch long, I put them in with the “big boys” in the tomato cage tower that is full of several types of freshly cut Milkweed branches stuck into water bottles. To keep my Milkweed from immediately wilting, I use a flower arrangers trick-flaming the cut ends so that the milky sap stops flowing. I use a small propane torch, like one that you would use for creme brulee. A match doesn’t cut it. It just isn’t hot enough to sear the ends to stop the sap which will make the branch wilt.

Flame the ends of Milkweed with a propane torch to stop it wilting

All it takes to keep your cats happy and healthy is a good supply of milkweed, because that is all that they eat-nothing else! Eat and grow is the primary goal for the caterpillar. The Monarch butterflies nectar on many types of flowers, but the caterpillars eat only Milkweed. There are lots of kinds of Milkweed, but it must be Asclepias, which is the Latin name for Milkweed. Go to Milkweed Guide to see great pictures and descriptions if in doubt. Growing Milkweed around the country to fuel the Monarchs is really vital to the Monarch survival and people are starting to grow it everywhere. Check out Got Milk…….Weed to read some amazing facts about this essential ingredient to raising Monarchs.

Milkweed is a source of food for many insects, most notably aphids and Milkweed bugs, which I wash off carefully before bringing inside. I don’t want anything else to be eating my collected Milkweed-just my caterpillars!

P1060588
Milkweed bugs covering Milkweed seed pods

Instars

Monarchs complete almost all of their growth during the larval stage which lasts from 9 to 14 days, during which time they undergo five larval instars or skin shedding. Before molting, the cat will become very still. If you catch this right after it happens, you can see the skin and then they eat it!

P1070100
This guy just molted and is getting ready to eat his skin

I try not to handle them at all, especially during this vulnerable stage as the larva spins a silk thread to keep attached to the leaf.  From hatching to pupation, monarchs increase their body mass about 2000 times!

By the time they are ready to pupate the caterpillars become these pudgy clown-like eating machines. So, move them to a large enough enclosure so that they can move to a flat surface, stick, or other hard surface to attach their chrysalis which is their last skin molting or instar. I place sticks in my cage to give the cats added surface area for the chrysalis.

 Making a Caterpillar Tower

Tomato cage enclosure
Tomato cage tower

As soon as I saw this ingenious enclosure at my workshop by The Monarch Teacher Network, made out of a tomato cage, black tulle, and clothes pins, I was hooked. Taking only a few minutes to slap together and tall enough for Milkweed plants, this was a great solution to keeping the cats contained while being able to observe them. Directions are below.

Directions for Monarch Tower

  • Buy a tomato cage with 4 rings. I used one that measured 14″ in diameter and 27″ from the first to the last ring in length. Cut half the length off of each protruding tine and bend the legs at the base inwards.
Start with a four ring metal tomato cage
Start with a four ring metal tomato cage, a 54″ square of tulle and some clothespins
  • Take your 54″ square piece of tulle and knot one end and pull that over top of your tomato cage.
Tulle pulled over the cage

  • Laying the cage on the side, clothes pin the tulle to the bottom ring of the cage pulling it taut. Using needle and thread, overcast stitch the tulle firmly to the bottom ring of the cage. Almost there!

  • Using 3 clothes pins, fasten the overlap area of the tulle on the side and place your cage on top of a pizza box base. If you aren’t a pizza lover, cut a piece of cardboard to fit the base.
    Use a cardboard base and set your Milkweed into a water bottle
    Use a cardboard base and set your Milkweed into a water bottle

     

  • Set up your cage on the base and it is ready to fill with your milkweed plant or cuttings. Tall enough for plants and lots of caterpillars, they will travel to the top when they are ready to pupate. This setup is easy to see through and clean, essential when you have lots of plump cats eating away.

    Change out your Milkweed when the caterpillars eat most of it
    Change out your Milkweed when the caterpillars eat most of it

Disease

I had a few cats die after turning black caused by a bacterial disease. This is upsetting but part of  life. I removed these as soon as I spotted them to stop any spread of infection to others. Be sure to clean and rinse your milkweed before using and clean your cage thoroughly every day to increase your caterpillar survival rates. If you notice a caterpillar looking sick, remove it from the others immediately. Once your caterpillar gets sick, there is really nothing that can be done. You can euthanize by placing in a ziploc into the freezer. For more information on caterpillar diseases, go to 7 Common Monarch Diseases.

Incredible Journey

Monarchs always amazed me with their unique migration, over 3000 miles in some cases, which seems an impossible task for such a delicate creature. The only butterfly that makes a two-way trip, Monarchs are unique in the animal kingdom. Unable to survive cold winter temperatures, the Monarch has evolved to make this incredible trek to over-winter in warmer climes, such as Mexico and southern California. Using a combination of thermals and air currents, Monarchs sense when it is time to travel and know where to go even though the migrating generation has never been to the distant over-wintering sites.

Primary Monarch overwintering sites

Map from USDA Forest Service

Monarchs travel along one of three major routes and investigators think that a combination of directional aids such as the magnetic pull of the earth and the position of the sun among others guide them. Monarchs can travel between 50-100 miles a day and it can take up to two months to complete their journey. Traveling only by day, Monarchs roost at night high up in trees to rest before warming up in the sun to continue their journey. A distance of 265 miles in one day is the longest recorded distance of a Monarch! A great website to track the migratory happenings of Monarchs and other animals is Journey North. Citizen Scientists record their observations all over North America to show the movements of animals north in the spring and south in the fall in real-time.

Many teachers include Monarch rearing in their science curriculum in Elementary school but I missed the opportunity in school and wanted to do it myself at home to observe the incredible transformation that these creatures go through. How can such fragile creatures make a 3,000 mile journey to an unknown location and remain there for months, mate and then return to the north to start new progeny?

Monarch rearing has been on my “must try” list for several years and a two-day Monarch workshop put on by MonarchTeacherNetwork got me motivated and ready to go. Milkweed growing, enclosure instructions, Monarch activities and games, healthy practices of raising, and release ceremonies were all covered in simple, easy to follow directions with added field trips to meadows full of Milkweed and a butterfly house. After the intense two-day workshop, I felt fully prepared to set up my own Monarch raising operation at home.

The hardest part of raising Monarchs is finding their tiny single creamy-white eggs which are smaller than pin heads. Carrying a portable hand lens on an overcast day makes it a little easier to spot the eggs in the field. If you observe Monarchs swooping in and landing on a Milkweed, there is a good chance that she just laid an egg.

Monarchs tend to lay their eggs singly on the underside of freshly grown leaves of Milkweed, hidden from predators and directly on their food supply for best survival rates.

The butterfly glues the egg on the leaf surface so that it adheres even through a rain storm, but predators find the eggs a tasty treat. The first egg for me was hard to find, but subsequent ones much easier once I knew what to look for. The likelihood of a Monarch surviving the egg and larval (caterpillar) stages is less than 10% in the wild. For great tips on finding eggs, go to How to Hunt, Gather, and Protect Monarch Eggs . This site gives great information on where, when and how to look.

After locating an egg, I note what type of Milkweed they were attached to and remove the leaf or branch and add it to my “nursery enclosure”, a small plastic container with holes poked in the top. Taking only 3 to 5 days to hatch, watch your eggs carefully as the caterpillar can emerge, eat their egg shell and will move on to fresher leaves pretty quickly. When the top of the eggs turns dark, hatching is imminent.

Adding some extra Milkweed leaves will keep the tiny caterpillars busy when they hatch. You could also place tulle or pantyhose over the top to keep any wandering minuscule caterpillars inside. Lining the container with a moistened paper towel makes cleanup of the “frass” or black gooey caterpillar poop easy and adds some moisture to their environment. Once inside the house, air conditioning tends to dry the air out for the caterpillars and a light mist from a spray bottle of water helps. I clean out the plastic container every day as the frass can bring in pathogens that can harm the caterpillars.

After the eggs hatch in about 4 days, the tiny caterpillars are no larger than 1/16 of an inch long. They are delicate and easy to overlook as you handle the Milkweed leaves, so move carefully when you are changing out old for fresh leaves.

Hedgehog Haven

An injured Hedgehog at St Tiggywinkles

On a recent trip to the UK, I visited St Tiggywinkles Animal Rescue near London to see the how the European Hedgehog is faring. Found across Western Europe into Scandinavia, reports from the last several years indicates that this native species is declining in much of the UK because of a variety of stressors.

St Tiggywinkles accepts all animals who need care, but the overwhelming majority are hedgehogs

Don’t confuse the native European species Erinaceus europaeus with the domesticated Hedgehog commonly found in pet stores here in the U.S. , a separate species. The European Hedgehog actually lives in tunnels and holes under hedgerows found throughout the UK. And they hibernate through the winter in a sheltered location.

The English Hedgerow Trust says, “Hedgerows are a fundamental part of the heritage of the British countryside, defining the nature of the landscape and providing a major shelter and food source for a huge variety of mammals, birds and insects. Hedgerows are effectively a vibrant ecosystem, a huge nature reserve in our small and (over) intensively farmed country.”

Hedgerows provide shelter for small mammals

Hedgerows are not commonly found in the U.S. like they are in Europe. Strips of bustling wildlife habitat for butterflies, birds, and bats, and many small mammals like mice, hedgehogs, and voles, they provide much needed shelter. Zigzagging across the English countryside composed of a variety of trees, vines, and shrubs, hedgerows can be a beehive of activity. A super habitat for wildlife, hedgerows help nature thrive in narrow strips through large fields, I would love to see more of these in the U.S. instead of fences. Providing sheltered routes along which wildlife can move freely across the countryside between fragmented woodlands, hedges also provide windbreaks and prevent soil erosion.

Formal hedgerow

Insectivores, Hedgehogs are very useful in keeping the grub and insect population down in UK gardens. Slugs are one of their favorite food, one reason I would love to have a family living on my property! Attracting Hedgehogs is easy;  encouraging wild areas and planting out native plant species. A source of fresh water like a pond, log/brush piles and  small houses will also help Hedgehogs to stick around and raise a family. Down in population by 30% in just ten years, the UK has established many rescue centers around the region to help with education and assisting distressed Hedgehogs.  And there are lots of Hedgehogs in trouble!

So Many Hazards

Covered in a coat of sharp pointy spines, the hedgehog will roll up into a ball when threatened by a predator.  Dogs and badgers are the main aggressors of hedgehogs. Smelly and grumpy, they are still appealing because of their snuffly little nose and beady eyes. Weighing up to 2 pounds, I was surprised how large they were, up to 10 inches long.  They are as big as a small dog!

Many more hedgehogs are killed and maimed by cars which is the main reason that they are brought to the rescue center. Also, hedgehogs hide in compost or brush piles, so people are warned to check their compost before turning it with a pitchfork as it is easy to impale a hedgehog with the tines. Likewise with bonfires, people are warned to check the brush pile before lighting it so that they don’t end up with a roast hedgehog! Open drains are another pitfall and if a hedgehog is caught, the advice is take two pairs of pliers and grasp the spines with these and lift it out gently to safety. String, barbed wire, and wire used in gardens can also become tangled up with the spines and enmesh them so they eventually starve. Garden poisons are commonly found to be ingested by hedgehogs which will kill them quickly. Wood preservatives that are frequently used on fencing can kill a hedgehog as they like to lick the fencing.

An all too common result of car encounters usually blinds and maims Hedgehogs so that cannot be released back into the wild as they wouldn’t survive. Hedgehogs in captivity often display pacing mechanisms to deal with the stress of captivity.

Hedgehog Friendly

Roaming far and wide, over 20 acres a night, in search of mates, nesting sites, and food, Hedgehogs need access to cut through fences and garden boundaries that are artificially set by humans. People are cutting holes in fences and adding tunnels underneath to help the population. Access to water sources is important but pools without ramps to climb out of can become deathtraps. Invertebrates that Hedgehogs feast on likewise are plummeting, so food sources are drying up. But people are setting out pet food at night for the creatures. An estimated 30 million Hedgehogs were roaming the countryside in the 1950’s; less than 1 million are roaming today. One glimmer of hope is that the decline in numbers is leveling off, perhaps due to conservation/education efforts. Go to Hedgehog Street to see what efforts are being used to wage war on Hedgehog declines.

Hedgehogs eat snails and slugs which are a scourge to many a garden

Hedgehog rescue centers are located throughout the UK just like St Tiggywinkles which I visited. Caring for over 10,000 sick, injured and orphaned animals per year just at St Tiggywinkles, these wildlife care centers are at the forefront of conservation and education efforts to stem the decline of Hedgehog numbers.

Tiggywinkles even has a parking lot in front for emergency lifegivers to get in quickly with their injured animals. Caring for not just Hedgehogs, but any wild animal in distress, they release any animals that are healthy back to the wild. Others who cannot make it stay at the center for life and are cared for.

Three For the Bees

Congregating on the front porch, my bees are hungry!
Pollinator container for early spring

#1

Pollinators are flying and searching for nectar and pollen to take back to their colony and the pickings are slim until the rest of the spring flowers open. Help them out with container plantings to supplement their foraging efforts.

Everything here I picked up at my local Lowes and/or Home Depot. Pick a large wide mouthed container  (18″ at least) and plant snapdragons, lavender, foxglove (digitalis), violas, and dianthus. I noticed once I potted this all up, that lots of bees, flies, and other insects started to visit immediately.

This container will remain on my patio all spring and once the foxglove, snapdragons,and violas are kaput, I will add some summer blooming plants to continue the show with the lavender and the dianthus.

#2

Another container which attracts many pollinators is the one above with primrose, scabiosa ‘Butterfly Blue’, heather, alyssum, woodland phlox, lilies, and yellow dogwood sticks for fun. The lilies will be the last to flower and will take this container into the summer. At that time, I will rejuvenate the container, keeping the plants that still look good and changing out the bloomed out ones. Makeover time!

Scabiosa ‘Butterfly Blue’ is a great pollinator friendly plant

#3

Violas are the star in this pollinator container. The silver ball is a great way to add “pizzazz” and amp up the impact. Again snapdragons are an important element for early spring chilly weather. The alliums will be blooming in another month to continue the color show. The cobalt blue container adds a splash of color to the composition.

Frost date for my area of the mid-Atlantic is May 12 so I am careful to plant only cold hardy plants –  no pentas, marigolds, lantana, coleus, etc.! I hold these until later in my greenhouse to fill in for my spent spring flowers.
