While visiting Mount Mitchell State Park in western North Carolina over the Labor Day weekend, I witnessed a native bee pressing open the lipped petals of the pink turtlehead (Chelone lyonii). It made me think of the importance of that moment and yet how that bee had already visited hundreds of flowers that day in order to collect pollen on the side of her legs. I quickly yelled to my son to come get an up-close view. This was a perfect opportunity to show him the importance of that little creature.
Insect pollinators may seem like a small part of our daily lives, but they have an enormous impact on us. Fortunately, gardeners’ interest in pollinators appears to be growing, as Duke Gardens saw when we offered pre-orders of a 6-plant “Pollinator Garden in a Box” preceding our Fall Plant Sale coming up on Saturday, Sept. 24. Within less than a week, we had reserved all 50 of the Pollinator Garden boxes we had prepared. We’ll have plenty of other pollinator plants at the sale, and the excitement over them is heartening for horticulturists like me, who are devoted to attracting pollinators to Duke Gardens and teaching visitors about these species’ roles in our lives.
Most people don’t realize that honeybees are not native to North America and that thousands of other insect species were responsible for pollinating many plant species before their introduction. Bees and wasps, flies, butterflies and moths, and beetles are among the thousands of plant pollinators across North America. These beneficial insects are responsible for all insect-pollinated fruits and vegetables that provide us with most of the nutritious vitamins and minerals that we need daily, and they also broaden our diets beyond just meat and wind-pollinated grain foods.
This act of pollination allows many types of plants to produce fruits and seeds, helping to create vigorous plants over many generations.
Approximately 75 percent of all plants in the world require animals for pollination. These animals are part of many humans’ daily diets, something worth keeping in mind as we seek ways to help the plants around us thrive.

If you’re excited about helping pollinators, try planting species that will bring them to your garden. “Attracting Native Pollinators,” by The Xerces Society, is a great resource to learn more. If you already have these plants, consider leaving perennials longer through the fall and winter for habitat. Many of these species will create nests within the dead stems of perennial species. Get creative and build pollinator houses or insect hotels. They’re similar to bird houses, but you leave off the front wall and pack it with small stems of bamboo so that solitary insect species can build nests inside. Remember, if you build it, they will come!
