Cultivation and Uses
USDA hardiness zones: 7-10. This plant dies to the ground in hard freezes.

Prune: After freezing temperatures are past, remove dead stems or cut nearly to the ground.

Mulch: Decomposing granite may improve growth. Small gravel may extend drought tolerance.
Mulch is undesirable with frequent water or rain because it will prevent the soil from drying quickly.

ground.
