Gardeners' Notes:

Positive growin On Nov 18, 2005, growin from Vancouver, BC (Zone 8b) wrote:

Almost non-iris like. Attracts alot of attention when in bloom. Easy grower that prefers a warm and sunny position with vigorous suckering habit. Breezes through winter despite its tropical origin. Adds an exotic look to a temperate garden with its almost palm-like stalks with foliage on the top. Recommended.

Positive jermainiac On Sep 22, 2003, jermainiac from Seattle, WA (Zone 8a) wrote:

Very prolific. Forms circular clumps of strappy foliage.
Flowers are fragrant! A delicate vanilla smell.

Easily propagated by division. Leaves tend to crack and brown in summer at the place where they flop over. Easily remedied by shearing and pulling the dead leaves.

I've seen this growing at the Royal Botanical Gardens in Edinburgh, Scotland.

Neutral Baa On Oct 20, 2001, Baa wrote:

A crested Iris from China.

Has fans of light-mid green, glossy, broad, sword like leaves borne on bamboo like stems which eventually lie flat and root. Bears white with yellow or blue markings, flattened, yellow crested instead of bearded flowers. Each flower stem can hold many flowers which bloom in succession.

Flowers April-June

Likes a moist, humus rich, fertile soil in sun or light shade. Not fully hardy will tolerate a minimum temperature of 23F.
