About Wrinkled Rush (Juncus rugulosus) 3 Nurseries Carry This Plant Juncus rugulosus is a species of rush known by the common name wrinkled rush. It is endemic to California, where it is a common member of the flora in many wet areas, such as marshes and riverbanks. This is a perennial herb growing in thick tufts from a horizontal rhizome. The stem is erect and green and has a distinctive wrinkled, rippled surface. It reaches a maximum height near 70 centimeters.

Each flower has reddish or brownish green petals with thin, transparent margins, and bristles at the tip. There are six stamens.
