Fringed iris is an herbaceous perennial rhizomatous plant in the Iridaceae (iris) family. It is an evergreen crested iris from Asia and can be found in forest margins and wet grasslands of Japan and China. The genus is named for the Greek goddess of the rainbow. The specific epithet means of Japan.
It is tolerant of a wide range of soil and pH types and needs good drainage in part shade. It is drought-tolerant and deer-resistant. It will readily spread by rhizomes to form clumps
The showy blooms appear in April- May and range from white to pale blue to purple petals with orange crests. The foliage is sword-shaped and evergreen. It has received the Award of Garden Merit from the Royal Horticultural Society.
Use fringed iris as a ground cover for semi-shady areas, such as under trees or in rock gardens. Give it room to spread.
Insects, Diseases, and Other Plant Problems: Too wet soils in winter can cause root rot.
