Growing:

USDA zone 8a through 9b. Needs a warm, frost-free situation. This plant blooms twice. It blooms on the previous year's growth, so resist the urge to prune it in early spring. However, if you garden in a place with cold winters, Mother Nature will more than likely prune the plant for you. It will bloom a second time on new growth.
