Description: It needs to be regularly cut back to promote new growth and flowering. It grows during warm weather, including during warm winter periods, and will die back partly at about 24F or fully at about 15F. So it does require a little work to look best, but is well worth the effort in return for profuse golden tubular flower clusters. After many years, the clump will grow to be unmanageable if lower limbs are not removed because it will readily layer itself.
