Iris tenax is a species of Iris, known by the common names tough-leaved iris, Oregon iris, or more colloquially, flag.
Distribution
It is native to southwestern
Description
Like many irises, Iris tenax has large and showy flowers. The flowers bloom in mid to late spring and are usually lavender-blue to purple, but blooms in white, yellow, pink, and orchid shades are known to sometimes occur.
The leaves are very slender for an iris, seldom over 5 mm broad; the plant is often mistaken for a type of
grass when not in bloom. Its rhizomes
spread slowly, causing the plant to grow in a tight clump.
Its species name (tenax) means "tough" or "tenacious" and is in reference to the strong, fibrous leaves of the plant, which were used by indigenous peoples for braiding into snares and other cordage.[4]
