Water regularly, especially during dry periods, ensuring the soil dries out slightly between waterings. Once established, it becomes more drought-tolerant. Avoid waterlogged conditions, which can lead to root rot.

Consistent moisture promotes better flowering and growth.

Prune back dead or spent flower stalks after blooming to encourage a tidier appearance and potentially a second flush of flowers. In late winter or early spring, cut back any winter-killed stems to encourage new growth.

Easily propagated from seed sown in spring, either indoors or directly outdoors after the last frost. Cuttings can also be taken in early summer and rooted in moist potting mix.

Repotting is generally not necessary for this perennial, as it prefers to be slightly root-bound. If it outgrows its container or becomes overcrowded, repot in early spring before new growth begins.
