I have just collected 20 Vigna caracalla seeds.
That makes 3 packages (2 p. with 7 seeds each and one randomly w/6 seeds) and will be sent anywhere worldwide. If you have some heirloom tomato seeds 'you feel the urge' to send me, they will be mostly welcome, but not excluding. I'm not necessarily looking for an exchange, I just want to share these wonderfully fragrant beauties. I grew mine from seeds and they are quite easy.
Although these babies are tropical, I know our Dave grows these and overwinters them indoors in a pot. I grow mine in an (app. 4 gallon) pot and leave them in the garden year round (I'm in an equivalent to a USDA zone 9b).
If you are interested, please Tree-mail me your address. I will post here when these offers are all taken.
