I live in Houston. Somewhere I was told my zone was 8B, due to the fact I'm in Noth Houston? Anyone able to verify, as there are so many zone maps, I am not sure who to believe, although we could be classed as 9, our area gets about 10* cooler at nights at times, than the rest of the area, like say, South Houston does. I searched for one here, but didn't see one? Thank you!
