Zig Zag Iris (Iris brevicaulis): Wild Southern Species

The Zig Zag Iris (Iris brevicaulis) is a distinctive wild species native to the south-central United States. Its common name derives from the zigzagging stem that bends at each node, creating a unique architectural form. This species thrives in wet, swampy habitats and blooms in spring with blue-violet flowers.
