Wild Iris is found in meadows
and along streamsides, often growing in colonies. Habitat is usually wet prior
to flowering but can be quite dry during the rest of the year.
Purple flowers are most common, but white flowers are occasionally found. Flowers
have six petal-like tepals. The outer three tepals are reflexed and have a yellow
stripe. The inner whorl of tepals is erect. Plants spread via rhizomes, which
contributes to their patchy growth habit.
