hey there.
just found this post after responding to your purple moosage and thought i would add some thoughts.
i have some upright indigo seeds, and i would be happy to share/swap. i have a good amount and would be happy to send them off to be planted, i am not sure i will even grow them even though i was originally looking forward to doing some dyeing.
i am interested in mostly tree seeds, fruit, actually i am interested in more than that.
i will include a link to a list i keep up of seeds i have to swap and what i am looking for, in case you would like to do a bigger swap of a few different things.
i have done a lot of seed trades on this site, so here is a detailed list:
