It prefers in well-drained, good-quality potting mix.
Water regularly throughout the growing season, keeping the soil evenly moist. After flowering is finished, water sparingly. Yellow leaves are usually a sign of overwatering.

It can be easily propagated by offsets or divide the rhizomes in spring for summer bloom.
