oh, really? I just thought that the zone hardness was for it growing, period. You mean, that if I tried something, say, oleander, which is a definite zone 7, and piled enough mulch around the base, that maybe it'll grow?
REALLY????? OMG.
If that's the case, then I'm DEFINITELY going to try some other plants that I swore wouldn't grow here (like Oleander.. I grew up as a child with our back fence totally blocked by Oleander.. it was over 15' tall and was the pink, white, & red varieties.. I would go and pluck flowers that were on our side of the fence to give to my mom. Never knew that they were toxic. But then again, never ate them, eithter).
YAY!!!!!!!! Learn something new every day!
