Optimal Growing Conditions
- Sunlight: Throws the best blooms in full sun, though it tolerates light partial shade.
- Soil: Thrives in fertile, moist, well-drained soil. It is highly adaptable and can tolerate poor soils, clay, or sand as long as drainage is adequate.
- Hardiness: Fully hardy across most temperate regions, surviving harsh winter frosts.
Pruning and Care
- When to Prune: Cut back immediately after flowering in late spring. Because it flowers on the previous year’s growth (old wood), pruning too late in the season or in winter will remove next year’s flower buds.
- How to Prune: Cut back the flowered shoots to strong lateral buds. Every few years, remove up to one-fifth of the oldest, woodiest stems down to the ground level to stimulate fresh, vigorous growth from the base.
- Maintenance: Low-maintenance overall. Apply a layer of mulch around the base in spring to conserve soil moisture.
