Water deeply but infrequently once established. Allow the soil to dry out slightly between waterings. Reduce watering in winter.

Prune to shape the plant and remove dead, damaged, or crossing branches. Best done after flowering to avoid removing flower buds. Avoid heavy pruning.

Easily propagated from seeds sown in fall or spring, or from cuttings taken in summer. Stratification may improve germination rates for seeds.

If grown in a container, repot every 2-3 years in spring. Use a well-draining potting mix and a pot only slightly larger than the current one.
