Plant Type:

Light: It depends on the climate you live in. For gardens at the cooler end of their hardiness range, they will thrive in full sun. For gardens at the warmer end of the range, it benefits from placement in afternoon shade.

Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. Soil pH does not affect flower color.

Water: Average water needs.

Fertilizing: Nothing special required. If desired, you may apply a granular fertilizer formulated for flowering woody plants in late winter/early spring when the soil is workable.

Pruning: Pruning is recommended in early spring. When the buds begin to swell noticeably, cut the whole plant back by one third. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time, just cut back to a set of leaves!

Other: It can be used as a cut flower! For its longest vase life, cut vertically up the stem about 2″. This will help it absorb more water.
