Cultivation and Uses
USDA hardiness zones: 8b-12. Damaged below 32°F. In zone 8b, in winter, must be in container moved indoors or next to south-facing wall where it will die to ground and revive in spring.
Heat tolerant: Yes.
Drought tolerant: Drought resistant.
Sun: Full sun.
Water once established: Every two weeks after first year. Soil must dry out between waterings. Excess water will reduce flowering.
Soil: Well drained, pH 5.6-6.0 (acidic). Adaptable, but enriched soil beneficial. High nitrogen fertilizer will reduce flowering.
Mulch: Heavily in fall in regions with winter freezes.
Planting: When planting, handle root ball with great care to keep it intact. Roots are very thin and do not hold soil together. After planting, water roots thoroughly, adding a root stimulator. Use flower fertilizer every two months until end of growing season. During the first year in ground, water regularly until winter, then keep almost dry.
Prune: In early spring, remove frost damage. Trim all branches back to 20' for best bloom.
Litter: High. Bract and leaf cleanup, pruning, training.
Propagation: Cuttings and layering.
