Cultivation details

Prefers a well-drained rich soil in a sunny position[1]. Plants are best lifted in October, stores in dry sand in a cool frost-free place over the winter and planted out in March[1]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233]. There has been some confusion over the name of this species. Iris decora Wall. should apply to a beardless species with the synonym of Iris nepalensis D.Don., whilst Iris nepalensis Wall. applies to a bearded species with the synonym Iris deflexa Knowle.&Wetc.

Plant Propagation

Seed - best sown as soon as it is ripe in a cold frame. It does not require cold stratification. Stored seed should be sown as early in the year as possible in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first year. Plant out into their permanent positions in late spring or early summer. Division, best done after flowering in late summer. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
