Cultivation and Uses
USDA hardiness zones: 7-11.

Soil: Well draining, dry, pH 6.1-7.8 (slightly acidic to slightly alkaline). Do not add soil amendments and do not fertilize. This plant is adapted to poor soil.

Seed can be placed in a sunny, well-draining spot in winter and left alone to sprout.
Litter: Low.
Propagation: Seed or cuttings.
Uses: Ornamental, screen, security hedge.
