Several years ago I received a large amount of seed of Fritillaria striata and distributed quite a bit of it through exchanges, but I still have some. Eddie McRae, the lily expert, once told me that Lilium seed could be stored for many years in a freezer provided it was in a glass, rather than plastic, container, so I put the excess away like that. A couple of months ago I sent some of the frozen seed to a grower in Scotland, and last week he wrote to tell me it had germinated very well six weeks after sowing. I've also grown Calochortus species to flowering from seed that had been frozen for as much as ten years. It is always worth acquiring and sowing seed even if the experts claim a particular genus or family cannot be stored. I now have 3 species of Trollius from the NARGS "leftover" distributions.

When I collect seed, I clean, put in paper coin envelopes and then into plastic zip locks and store in the fridge. Lily seed, for example germinates well even after several years as do cyclamen and others. > > Is it ok to donate seed of uncommon plants if a year old or less and stored in proper conditions? I know Alan at Alplains carefully stores his seed and continues to ship some of it for 2-3 years. It almost always germinates, and any failures are usually mine. > > _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net> PBS Forum https://…
