Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter, especially if grown in cooler conditions.

Ensure good drainage to prevent root rot, as this species is drought-tolerant once established.

Prune after flowering to maintain a tidy shape and encourage a second bloom. Cut back flowered stems by about one-third. In early spring, remove any dead or weak stems.

This promotes vigorous new growth and prevents the plant from becoming leggy.

Propagate by semi-hardwood cuttings taken in summer or by seed sown in spring. Seeds may require stratification. Cuttings usually root well in a moist, well-drained medium.

Division of established clumps is also a viable method in spring.

Repot infrequently, only when the plant becomes root-bound. This is typically every 2-3 years for container-grown specimens. Use a well-draining compost mix, such as sandy loam.

Repot in spring before new growth begins for best results.
