I didn’t see an answer to this in reply, so just in case you missed the big swap, or someone else stumbles upon this thread:
So far we’re doing one big pooled-seed swap per year, where everyone sends in their seed in fall/winter. This year (winter 2022/2023) was great, and next year we are considering doing more categories to potentially include climate, resistance, etc though that’s not yet for certain.
Seed that didn’t get taken by the members of the swap may be further available this spring.
Meanwhile, if you want to jump right into seed sharing, @UnicornEmily is coordinating a seed train here as of this writing: Serendipity Seed Swap!
