Iris tenuis
Iris tenuis (Clackamas iris) is a plant species in the genus Iris, subgenus Limniris. It is a rhizomatous perennial, endemic to Clackamas County, Oregon. The flowers are white, pale blue or lilac, with a yellow or golden low dissected crest and pale green leaves. It is cultivated as an ornamental plant in temperate regions.
It is cold hardy, but not heat or dry hardy. It is less hardy than other crested irises and is more difficult to establish in the UK.
It is hardy to Europe Zone H2, and between USDA Zone 6 to Zone 9.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.
