Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

This iris blooms late spring, with a more delicate and refined form than the bearded iris. The flower has six segments, with three recurved and three standards (the petals that stand upright). Flower colors are white, blues, purple, rose, and violet. The foliage is narrow and dense, eventually having an upright vase-shape. The flowers, when they go to seed, produce beautiful orange berries that are persistent into winter, and the foliage develops an orangish tone in the fall. Grows about 2 to 4 feet tall and 18 to 24 inches wide. Truly, a three season iris.
Grow in full sun to part shade in well drained soil. Though it is not particular about soil type, it will grow best in a fertile, loamy soil. The flowers are lovely cut, but the seed heads are quite ornamental and its worth letting some go to seed. The foliage is very persistent into the winter months and provides a pleasant winter presence; cut back in late winter to early spring as new growth emerges.
