- Description
-
Japanse iris is an herbaceous perennial rhizomatous plant in the Iridaceae (iris) family. It is an evergreen crested iris from Asia that can be used in the semi-shady woodland garden as a ground cover. It will spread quickly to cover an area. The showy blooms appear in April- May and range from white to pale blue to purple.
It is tolerant of a wide range of soil and pH types and needs good drainage in part shade. This drought-tolerant plant is generally avoided by deer and rabbits.
