Keep the soil consistently moist but not waterlogged during the growing season. Reduce watering significantly in summer dormancy, allowing the soil to dry out between waterings.

Ensure good drainage to prevent root rot, especially in container plants. Overwatering is a common mistake.

Deadhead spent flowers to encourage further blooming and maintain a tidy appearance. After flowering, trim back any yellowing or dead foliage.

In autumn, cut back the entire plant to the ground level to prepare it for winter dormancy and promote healthy new growth next spring.

Best propagated by division of tubers in late summer or early autumn. Carefully lift the clump, divide into sections with at least one bud, and replant immediately.

It can also be grown from seed, but this method is slower and less reliable for hybrids.

Repot tubers every 2-3 years in late summer or early autumn, just before new growth begins. Use a well-draining potting mix, such as a blend of peat, loam, and grit.

Choose a pot that allows for some expansion of the tubers and provides excellent drainage.
