In this webinar, Chris Sanford (Yonder Hill Farm) reviews the taxonomy and biology of cucumbers, squash (cucurbitaceae) and kale (brassicaceae). She also addresses considerations such as isolation distance, minimum population, seed longevity, seed processing/cleaning, and more. This webinar, facilitated by Steph Hughes, was hosted jointly by ACORN and The Bauta Family Initiative on Canadian Seed Security, in 2016, to support seed library collections in Atlantic Canada.
