Favorite unusual or (not so common) perennials for the south
It seems like most every time I read the perennial forum, most of the posters are from much cooler zones, or from more moderate summer areas like the PNW. A lot of the stuff they like just does not bloom or look all that good in the dead of summer here. And then when I visit some of the regional forums, much of the talk is about coneflowers, mexican petunia, yaupon holly, crape myrtles, lantana, etc.
So, besides the usual suspects -- what are you growing that is a consistent perennial performer in the south, having either great blooming and/or wonderful shaped or colorful foliage?
