$10 Connecticut Horticultural Society Webinar: Digging Deeper into Ecological Horticulture with Uli Lorimer

October 15th 2026 | 7:00 pm

REGISTER HERE FOR $10

What is Ecological Horticulture? What distinguishes it from mainstream horticulture? Why is genetic diversity important? Ecological Horticulture takes a different approach from traditional gardening by focusing on nature-friendly principles. This talk will dive into key ideas and challenge common gardening practices. For example: Why is genetic diversity essential? Can I use cultivated versions of native plants? How should climate change influence my gardening choices? These questions and more will guide a discussion on creating and caring for gardens in harmony with the environment.

Uli Lorimer serves as the Director of Horticulture for the Native Plant Trust, a leading non-profit dedicated to preserving the native flora of the Northeastern United States. In this role, he oversees the acclaimed Garden in the Woods in Framingham and Nasami Farm in Western Massachusetts, which focuses on native plant propagation and research. Uli’s impressive career includes positions at the National Arboretum, Wave Hill, and as the Curator of Native Plants at the Brooklyn Botanic Garden. A lifelong enthusiast of plants and biodiversity, Uli continues to study the region’s ecosystems, collect seeds from the wild, and introduce new plants to collections.

He is also a prolific author and speaker, well-known to audiences across the horticultural community. His publications include Tough Natives for Tough Places and A Native Plant Reader. His latest work, The Northeast Native Plant Primer, reflects his deep commitment to native plants and their ecological value. With a science-based approach and a passion for biodiversity, Uli offers invaluable insights into selecting plants that maximize the ecological impact of our gardens while celebrating the beauty of native flora.
