I have individual packets (24+ seeds/pack) or large quantities (hundreds of seeds) of fresh Baptisia australis seeds for trade. I would be fine with sending all of these to one single trader for just one trade. Somewhat unusual tree, shrub, or perennial seeds that are hardy in zones 6b to 7b, aren't
invasive (not on the TN-EPPC's list), and not prone to a lot of disease
and insect problems are my preference. Will also consider sending just one pack at a time, but I'm not sure it will be worth the postage that way.
