The signal is triangular, whitish-yellow to whitish green patch and occurs basally on the sepal. The petals are spreading perpendicularly to slightly ascending and are smaller than the sepals. The inflorescence is multi-flowered on a ziz-zag stem with two terminal flowers and is hidden down among the leaves. The bright green leaves are lax and arching, arising from shallowly rooted, branching rhizomes that can form large colonies. *Iris brevicaulis* is commonly found growing in swamps and wet meadows.
