Cultivation and Uses
USDA hardiness zones: 8b-11.
Heat tolerant: Yes.
Drought tolerant: Yes.
Sun: Full sun. Shade causes sparse leaves and leggy growth.
Water after becoming established: Once every month or two.
Adapted to regions with unreliable rains, and does not like
excessive or frequent water. Always water at drip line
(under tips of branches farthest from trunk) to encourage
sideways root growth.
Soil: Well drained, dry, low in organic content, pH 6.1-9.0
(slightly acidic to highly alkaline). *Do not use a nitrogen
Mulch: Not necessary. Allow light leaf litter from plant,
but avoid heavy accumulation because of fire danger.
Prune: Lightly, periodically, never more than 30% of crown,
and do that in winter to avoid sunburn that encourages insect
infestation. Less is better, even with hedge uses.
Propagation: Scarified seed.
Uses: Ornamental, shade, xeric garden, hedge, screen.
Very long lived in native environment. A tough plant,
but does not regrow if burned in a wildfire, and should not be
placed in a wildfire prone area.
