Keep the soil consistently moist, mimicking its natural boggy habitat. Water thoroughly when the top centimeter of soil begins to feel dry.

Avoid letting the plant sit in standing water for extended periods, as this can lead to root rot. Reduce watering slightly during cooler, dormant periods.

Prune to maintain shape and remove any dead or yellowing foliage. Pinch back leggy stems to encourage bushier growth. Pruning is best done in spring before new growth begins.

Remove spent flower stalks to prevent seed formation and direct energy back into the plant's health.

Propagation is typically achieved through division of established clumps in spring. Carefully separate the rhizomes, ensuring each section has roots and at least one growth bud.

Replant divisions immediately into moist, well-draining soil. Softwood cuttings can also be taken in late spring.

Repot young plants annually or every two years, and mature plants every 2-3 years, preferably in spring. Use a well-draining, acidic potting mix, such as a blend of peat moss and perlite.

Choose a pot that is only slightly larger than the current root ball.
