MOUNTAIN MINT IS A GREAT PLANT FOR POLLINATORS

       Over the years, my wife and I have been planting a diversity of nectar/pollen-producing plants in our gardens. This has been done in an effort to provide our backyard pollinators with sources of food throughout the year. This approach has offered us the opportunity to watch pollinators feed at a parade of plants from week to week as well as season to season. As the blossoms of one plant wither and die, pollinators redirect their attention to plants that are currently blooming. Right now, many of these pollinators are visiting mountain mint (Pycnanthemum sp.), one of the more recent additions to our landscape.

       Mountain mint is a native perennial herb that grows two to three feet tall. Eight species of this hardy plant are found in the Southeast. Plants grow two to three tall. They exist in a variety of soil conditions, including the dry clay soil found in our yard. While the plant does best in moist soil types, it is drought tolerant. Mountain mint will grow in partial shade as well as full sun.

    Mountain mint has a unique, eye-catching appearance. What makes this plant stand out is the fact that the leaves growing just below its flowers look like they have received a dusting of powdered sugar. In fact, to me, this foliage is far more attractive than the plant’s small white-purple blooms. In fact, these blossoms or so small you might overlook them if they were not arranged in clusters.

       However, though mountain mint plants won’t win any awards for beauty, the fact that it blooms from June into October makes it an important source of food for wild pollinators.

       Speaking of awards, in 2013 the Penn State Extension Service evaluated 88 pollinator-rewarding perennial plants for their importance to pollinators. At the end of the trial, mountain mint (P. muticum) received the highest rating for longevity of flowers, diversity of pollinators that use the plants, and the most insects attracted during the trials. In one trial, 76 insects visited the plants in just two minutes.

       I am not surprised at these findings. When my wife and daughter found our mountain mint blooming a few days ago, they saw a stand of mint being visited by three species of butterflies (juniper hairstreak, red-banded hairstreak, and pearl crescent). They competed with the likes of thread-waisted wasps, hornets, and bumblebees.

       One thing I like about mountain mint is that it is easy to grow. A friend gave us some mountain mint plants two summers ago. We set them out and kept them watered. The very next year the plants produced a crop of flowers.

       If you like to create dried arrangements, you will love mountain mint. Each fall after the flowers have disappeared, you are left with scores of unique prickly, round, brown seed heads displayed on long stems.

       Mountain mint is a plant that definitely deserves a place in your flower gardens.
