Bloom period
Care guide
Plant in full sun in well-drained, neutral to slightly alkaline soil. The rhizome should sit partially above soil level. Water sparingly — wet feet are fatal. Apply a light, low-nitrogen feed in spring.
Pruning tips
Remove spent flower stems immediately after blooming. Trim damaged or yellowing foliage in summer. Cut leaves back to a fan of about 15 cm in autumn. Divide rhizomes every three to four years after flowering.
