Plant Pick: Siberian Iris

by Vancouver Island Master Gardeners Association

Latin name:  Iris sibirica (white)

Common Name:  Siberian Iris

Considered to be one of the finest Siberian Iris.  It creates a lovely display of ivory -white, rounded ruffled flowers with golden centers. The flower is on a long stable stem well above the leaves and makes an excellent cut flower.

The Siberian Iris are an easy, trouble-free group, forming clumps of grassy foliage with a late spring display of butterfly-like flowers. Plants are sturdy and upright, and seldom troubled by Iris borer. This taller selection has a lavish display of clear white flowers. Excellent at the waterside, or in a moist border. Also suitable for using in tubs and mixed containers. Siberian Iris are tolerant of wet sites, and will even grow in the shallow water at the edge of a pond or stream. Striking addition to any garden, blooming late Spring into the Summer. Cut the dying foliage back in late fall. Easily divided in early fall, every 3 to 4 years.
