Iris 'Kumo-No-Obi' Overview

Iris ensata 'Kumo-no-obi' or the Japanese Water Iris is a deciduous perennial that produces stalked clumps of lance-shaped medium green leaves. In summer erect stems bearing dark-purple flowers appear. The "falls" - the three outer petals are attractively marked with basal yellow areas. Iris 'Kumo-no-obi' is a sun-loving, fully hardy plant that will also tolerate partial shade. Growing from underground rhizomes, it is happy growing in damp soils, making it a suitable plant to grow along watersides, in boggy damp soils as well as garden borders. Needing little care, flowers can be removed from stems as they fade, and dead or dying leaves can be cleared as needed. Some people have experienced skin irritation when handling this plant; wearing gloves is advised. Keep an eye out when young children or pets are near as all parts of this plant are toxic, causing discomfort if eaten.
