How to Grow

Cultivation

Grow in well-drained, fertile, neutral to slightly acid soil in full sun. Do not cover the rhizomes with mulch, or allow other plants to shade them; sun on the rhizomes encourages flowering. Give a high-potash feed in spring and divide every three to four years. See also Bearded iris cultivation

Propagation

Propagate by division of rhizomes from midsummer to early autumn; see Dividing irises
