Type: Rhizome. Exposure: Full sun. Bloom Time: Early Summer
Description: Hardy, easy to grow. Attracts butterflies and hummingbirds. There are some 300 species in the genus Iris. The flowers have three large outer petals called “falls” and three inner upright petals called “standards.” The falls may have beards or crests. Bearded iris are so-called because they have soft hairs along the center of the falls. In crested iris, the hairs form a comb or ridge.
Soil and pH: Prefer fertile, neutral to slightly acidic, well-drained soil. Keep rhizomes exposed. If covered with soil or crowded by other plants, they'll rot.
Garden Tips: Don't trim iris leaves, they carry on photosynthesis for next year's growth. Cut off brown tips and cut the flowering stalk down to the rhizome to discourage rot. When clumps become congested or lose vitality, divide and replant sound rhizomes in fresh soil. The best time to replant irises is soon after bloom. Irises need at least half a day of sun and well-drained soil. Without enough sun, they won't bloom.
