Please don't jump on me for asking here ... I'm hoping someone has had experience, is all. I have searched -- the web, gardening books and software, but I'm suffering from information overload and confusion.
Can anyone recommend a shrub, preferable flowering at some point, that won't exceed 6' tall by 6' around that can take 100 degree summers on a Southern exposure that gets full sun all day? In in zone 5, but if this heat keeps up it'll be zone 6 very soon.
Thanks ...
