Growing notes

Light

Full sun or partial shade. In hot, humid places where nights stay above about 21 °C it is short-lived, so give it shade from the hottest sun there.

Soil

Fertile, well-drained loamy, chalky or sandy soil; it suffers in soil that is too wet or too dry and does not survive wet winters.

Care

Plant 30–35 cm apart. It likes cool roots — mulch around it and water in dry weather. Remove spent flowers to keep it blooming longer. Divide clumps every two to four years in spring or late summer to keep them vigorous; division is also the easiest way to get new plants, as raising it from seed may not be reliable. Protect it from slugs and snails, and watch for rust, powdery mildew and leaf spot.
