A tufted  [http://en.wikipedia.org/wiki/Perennial_plant perennial] with narrow, grass-like leaves and showy flowers on thin, wand-like stems to 14 in. tall. Leaves slightly exceed the flower stem in height. The flower of this species shows considerable variation in color, from white to deep purple.

Description

Clump-forming herb growing from branched rhizomes, up to 3 dm tall.[2] Stems are solid.[3]

Basal leaves reach up to 45 cm, cauline leaves reduced, more or less erect, up to 15 cm. long, sheathing the stem for up to half their length.[2]

Sepals (the outer 3 segments, reflexed, sometimes referred to as "falls",) have pronounced veination and usually bearing a yellow "signal". Style branches, petalloid, opposite sepals and curved over them.[3] Ovary inferior.

Fruit is an oblong, 3-sided capsule, 3-5 cm long.[2]

Genus name comes from Greek Iris, rainbow.[3]

Bloom Period

June - August[4]

Distribution

Grays Harbor County and south Puget Trough, Washington, southward in western Oregon, to northwest California.[3]

Habitat

Prairies, meadows, and open woodlands, lowland to upper montane zones.[3]

Uses

Tolowa Dee-ni’ use to make cordage.[5]

There are several uses of the root in herbalism, but fresh root preparations are extremely harmful. Preparations should only be made with the completely dried root, and administered by a skilled herbalist, as even fresh preparations are low-dose.

Propagation

Iris tenax does not spread quickly, but will form large clumps of underground bulbous stems. It requires wet soil in the spring time and well drained soil during the drier months.[6]
