Cultivation

They are fully hardy, but some groups may thrive only in specific growing conditions. All irises are best planted in late summer and early autumn. Outdoors you can grow them in well drained, fertile, neutral or slightly acid or alkaline soil in full sun to lightly dappled shade. In order for irises to thrive, most of them need long, hot summers. Irises that require protection from rain or frost should be grown under glass.

Propagation

By division of rhizomes or offsets in late summer or by seed in autumn. Certain cultivars should be propagated by division only.

Pests, diseases or disorders
