Mt Cuba Center Webinar: Planting for Specialist Pollinators

June 23rd 2026 | 10:00 am - 11:15 am

REGISTER HERE FOR $25

Specialist pollinators need our help more than ever. While generalist bees and butterflies can use a wide range of plants, many caterpillars, bees, and other insects rely on very specific native species for food, shelter, and reproduction. When those plants disappear from our landscapes, the pollinators that depend on them disappear as well.

In this class, you’ll learn how to make a meaningful difference right in your own backyard. Discover the essential trees, shrubs, and wildflowers that support specialist pollinators—and how even small additions to your garden can create vital habitat. Instructor Leah Brooks will introduce a diverse selection of native perennials and highlight the remarkable relationships between these plants and the specialist species that rely on them for survival. Leave inspired, informed, and ready to support specialist pollinators through thoughtful, impactful plant choices.

Virtual class ends at 11:15, as the instructor takes the in-person students for a tour of the gardens. All virtual registrants will receive a recording of the class with access to view the class for 30 days after the live session.
