Best grown in loose, medium moisture, well-drained soils in full sun. Plant in sheltered locations north of USDA Zone 7. In USDA Zones 5 and 6, this tree/shrub often suffers winter die back or dies to the ground in severe winters. It is not considered reliably winter hardy throughout USDA Zone 5. However, even though plants may die to the ground in Zone 5-6 winters, the roots often survive the winter and push up as much as 5' of new growth the following year. Because flowering appears on new growth, this shrub also may be regularly pruned to the ground in early spring and grown in the manner of an herbaceous perennial
