I think Bluespiral has a point that we need to have someplace on the swap list for wishes.
I have more seeds than any normal person should ever have. Especially someone with a tiny yard. So I'd be overjoyed to give more seed than I get! I need the room! Even if they didn't have anything I wanted I'd be happy to gift them some seeds.
Most people in the city buy plants for their gardens so I can't even give seeds away.
