Comments Because the flowers last a short time, this shrub is more functional than ornamental. Its ability to form dense thickets has made it useful in stabilizing dry, sandy areas and preventing erosion. Suffers from frequent disease and insect problems and needs protection from wind, as it is easily broken.
