Germination Guide Overview
This guide provides recommendations for the germination of over 8000 seeds listed in the seed exchange of the Ontario Rock Garden & Hardy Plant Society between 1995 and 2020. For each species, a single germination technique has been chosen from several successful approaches for dry seed stored 6 months @ 20°C, except where noted.
While this data is based primarily on the experience of ORG&HPS members, we have also relied extensively on methods described by Norman Deno (Seed Germination Theory and Practice), Dr. Pavel Slaby ( www.kadel.cz/flora ) Tom Clothier ( http://tomclothier.hort.net) and Gene Mirro, an authority on lilies. We are continuing to collect complete data on many species.
