Iris japonica

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.
