Pollinator Planters: Container Gardening for All Conditions will take place on Saturday, Sept. 27, from 10 a.m. to 11:30 a.m. Pollinator steward Heather Andrews will teach attendees about migrating creatures and how to create take-home gardens for a variety of weather conditions. She will discuss host plants for native butterflies and birds, which plants are best for hosting the most pollinators possible, strategic combinations of plants, and the benefits of delaying spring cleaning in a garden.

Andrews will create two demonstration pots designed to attract migratory butterflies and hummingbirds. At the end of the class, attendees will select three plants to customize a sun or shade pot of their own that will help energize migratory species passing through their yards in the fall.

Foraging Focus: Goldenrod will be held on Sunday, Sept. 28, from 10:30 a.m. to 3 p.m. In the first part of the class, attendees will learn about goldenrod as a source of food, well-being, and ecological understanding. They will look at plants in the field to practice identification, species differentiation, ethical harvest, and preparing medicine. Attendees will then enjoy lunch along with freshly brewed goldenrod tea. In the second part of the class, botanical dye artist Chelsea Thompson will show how to transform gathered goldenrod into wearable colors. She will cover the foundations of using local blooms to dye natural fibers, practicing two methods, shibori and bundle dyeing, on two clothing or fabric items that attendees bring to the class.
