Oh no... those things are the Devil! I mean, yes, they are technically edible, but they are awful. We have them all over the place here, and they shoot needles at you from across the yard, (with magic, I think!), and some of those needles are invisible and impossible to remove!
If I were in a survival situation, I guess I would try to eat them, but for now, they are the worst! I am all for propagating edibles, but not these.
When we first moved here, we thought, how cool! Cacti in the yard!!!
Many, many needles and tears later, it is actually not cool at all...
:(
I hope that my venture goes better than yours. OUCH!
Haha I hope so too! Best of luck!
Fun fact: If you run over them with a mower, they will get chopped into a zillion pieces. Each piece will grow a new stabby-booby-trap... I mean, cactus.
Hopefully the variety you're growing is better, and hopefully being farther north, your winters will keep them from running amok. ;)
