Our Native Irises: Louisiana Irises
Iris brevicaulis: Zigzag Iris
The zigzag iris occurs from Ohio southwest to Nebraska, south to Texas, east to Florida and north to Kentucky.
Iris brevicaulis has a bluish-purple to light bluish-violet flower and rarely occurs as a white form. The sepals are widely spreading and arching downward. 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.
