They did not grow so freely grow back in the depths of the mountains when I was learning about the 'edibles', Kent, and if I didn't eat them then, I haven't eaten them today. I might try that, though, since they are in full bloom.
Soapy sounds much like the flavor of Bouncing Bet, Saponaria officinalis, I think.
I also think Yucca filamentosa is what's here, but not so much in the far eastern part of KY. Major difference in climate and I suspect it prefers this warmer drier climate that's far west. (Not so dry right now, thinking of building an ark.)
So interesting about the pickled pistils! But I don't think I'll try it.
Thanks!
