Twelve years ago the U.S. Senate’s unanimous approval and designation of a week in June as “National Pollinator Week”, marked a necessary step toward addressing the urgent issue of declining pollinator populations. Pollinator Week has now grown into an international celebration of the valuable ecosystem services provided by bees, birds, butterflies, bats and beetles.
The NPGN’sregistered over one million new pollinator gardens in just the last three years. They salute Washington-Arlington-Alexandria area for being a Top Pollinator City with 13,493 registered gardens. The NPGN is encouraging everyone to plant three new pollinator-friendly plants, one plant for each season to ensure a consistent food supply for pollinators.
To make it easy to figure out what to plant, you can ask at native plant sales, visit nature centers, and go to websites like plants.usda.gov. This website has regional and state lists of native plants that you can plant in your area which includes trees, shrubs, vines, and herbaceous plants.
Here are my three top picks that span the seasons:
Possessing outstanding mildew resistance of shades of lavender-pink flower clusters, this native phlox is a star in my garden and always draws a lot of interest from visitors. Pollinators cluster around the heads constantly, providing a show for weeks in the mid-summer, and giving me lots of photography opportunities. Ranking at the top in ecological and horticultural trials, this plant should be in many more gardens.
Just listen to this rave review from Mt Cuba Center in Delaware who has trial gardens testing for usefulness, beauty, and pollinator visits.
“Phlox paniculata ‘Jeana’ is, without a doubt, the best-performing phlox from the trial. This cultivar was discovered growing along the Harpeth River near Nashville, Tennessee and named after its discoverer, Jeana Prewitt. Although there were many plants of Phlox paniculata in the area, ‘Jeana’ in particular stood out for its exceptionally mildew-free foliage. This trait carries through to the garden and is one of the main reasons ‘Jeana’ performed so well in the trial. This 5′ tall beauty also produces an impressive floral display from mid-July through early September. Interestingly, the individual flowers, or pips, are much smaller than any other garden phlox. However, that does not deter the butterflies that feed on its nectar. In fact, we found ‘Jeana’ attracted more butterflies than any other garden phlox in the entire trial. With a top rank in both horticultural and ecological evaluations, Phlox paniculata ‘Jeana’ is hard to beat.”
A taller flower topping out at 4′ to 5′, I love grouping these plants for a big show of flowers plus pollinators. Sometimes staking or some kind of support is necessary, like helpful supporting plants surrounding your clump. One of the only phlox paniculatas that I know tolerating deer browsing, it is a useful landscape plant for the perennial border. The lavender pink shade goes well with many other colors and the plant behaves and doesn’t spread aggressively.
Another top choice is a little-known mint, called Mountain Mint which blooms for 15 to 16 weeks.
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.
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.
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.
Attractive to both hummingbirds and bees as well as humans, Bee Balm is one of my favorites as an early summer bloomer and easy to grow perennial. Commonly known as Bee Balm or Monarda, Bee Balm is “balm” to all flying insects and enjoyed by humans in teas and potpourri. Each flower head rests on a whorl of showy, pinkish, leafy bracts. Flowers are attractive to bees and butterflies.
One of the 21 superstar pollinator plants that I designed my poster with, and available at TheGardenDiaries Etsy shop, Bee Balm is a pollinator superstar and always has many insect visitors on a sunny day.
Other common names include horsemint, oswego tea, and bergamot, the latter inspired by the fragrance of the leaves, which is reminiscent of bergamot orange (Citrus bergamia). Bergamot orange is the flavor that gives the unique taste of Earl Grey tea.
From the roots, up to the flower, the entire plant has a spicy minty fragrance which quality repels deer and other browsing critters.
A valuable plant for landscaping because of this repellent attribute, Bee Balms now come in petite and dwarf sizes to fit into smaller gardens. Even though the entire dwarf plant is smaller, the flowers are the same size or larger than some of the taller varieties.
Although bee balm appears to have thin narrow petals, close up they are really little hollow tubes perfect for thin beaks like hummingbirds. “Leading Lady Plum’ has a scattering of dark plum spots on the tips of the petals, adding another color dimension to this standout variety.
The “flower quotient”, a term I use for the relative size of the flower to the size of the foliage, is greater than most flowers. When a Bee Balm blooms, it is stunning, unusual, and one that stops visitors in their tracks.
The red variety is commonly known as Oswego Tea. Used by colonists in place of English tea after the Boston Tea Party, when they threw the English tea in the harbor to protest high taxes. Bee Balm continued for years as a medicinal and enjoyable tea and was frequently planted next to colonists homes for ease of gathering. To make your own tea, just air dry some leaves and steep them in hot water.
Coming in an array of colors and sizes, you can find a Bee Balm for any size garden now, some even fitting nicely into containers. Hybridizers have been busy with this plant and every time I go to the nursery, I see another small variety pop up. “Small” is the key word here; Most plants being developed now have a shorter stature and larger more colorful flowers to appeal to gardeners with limited space gardens or containers.
Because of the diminutive size of the new varieties, I tuck them in when I have a bare spot in the garden. Enjoying some shade in the afternoon in hot climates, these workhorses will bloom their little hearts out-usually lasting for 2 months or more if you dead head. The larger varieties can spread aggressively and should be controlled before they encroach and overtake other perennials.
Prone to downy mildew which can mottle the leaves, the newer varieties are more resistant to this disfiguring but not fatal disease.
