The Siberian Iris are an easy, trouble-free group, forming clumps of grassy foliage with a late spring display of butterfly-like flowers. These species of plants are sturdy and upright, and seldom troubled by Iris borer. This mid-sized selection has bicolored flowers of buttery-yellow and white, and repeat blooms. They are very good 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. Easily divided in early fall, every 3 to 4 years. Be careful: Harmful if eaten.
