Does anyone have suggestions for a shrub/bush that has flowers in a shade of blue to purple that will grow well in full sun? I would really like to use a butterfly bush, but it appears that it can only be planted down to zone 9.
Does Crepe Myrtle do well in your zone? I have seen some pretty purple colored ones.
I think Mexican Petunia would probably grow well in your zone, probably too well, haha.
