...cold hardy down to 12 Farenheit? i might need to try growing this. we almost never get winter overnight lows lower than that.

digging a little, i see it reccomended for zones 8-9; we're in 7b here in central NM. i have a very sheltered side-yard that we think is a tiny micro-zone 8 because so many things grow differently there (and we successfully overwinter dahlias in the soil there but not elsewhere). maybe we can put it there!
