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.
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.
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.
