I can't believe I'm posting this. WW seemed to think someone might be interested.
This spring I'll be digging up my 8x10' patch of Opuntia (Prickly Pear cactus). I do not know what type they are. They're hardy here in zone 6a, bloom yellow every spring and the bees love them.
If any brave souls would like some, I'll send them for shipping costs. Buy your own gloves and planting tongs.
