Care Notes

Plant in average to moist, well-drained soil. Drought-tolerant once established. Blooms on old wood; prune soon after flowering, not in fall or winter. Prune hard every 3-4 years after bloom to renew vigor and prevent a leggy base. Deer and elk browse this plant in winter, so protect young specimens in high-pressure areas.
