Growing:
USDA zone 5b through 8b.  Plant in sun or partial shade.  Suitable for growing in a container.  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.
