Allow the soil to dry out slightly between waterings. While it tolerates some drought once established, consistent moisture, especially during dry periods, promotes healthier growth.

Avoid waterlogging, which can lead to root rot. Water at the base of the plant to keep foliage dry.

Pruning is typically minimal. Remove any dead or damaged foliage as needed to maintain a tidy appearance.

Deadheading spent flower stalks can prevent unwanted self-seeding if you wish to control its spread, but it's not essential for plant health.

Propagation is easily achieved through seeds sown directly in the ground in spring or autumn. Seeds germinate readily.

It can also be propagated by division of established clumps in early spring or autumn, although this is less common.

Repotting is rarely necessary for this species as it is typically grown as a perennial in the ground or in containers where it is unlikely to become root-bound quickly. If grown in a small container, repot in spring to a slightly larger pot with fresh, well-draining soil.
