I'm in zone 8 and do like this plant. It seems to be somewhat less overwhelming to other plants than zulu's maybe because I'm in zone 8. Of course , it depends on what kind of winter I have. It is pretty easy to start new plants from cuttings if you need to down size. I like the fact that it changes thru the summer in flower color. Mine usually starts out all red, turning to red and white, then all white, then back to red and white. It make s a big statement. I really don't mind the scent.
