Diplarrena is a group of evergreen perennials with rhizomatous growth, closely associated with irises. These plants form clumps characterized by rigid, linear to sword-like foliage that can reach heights of 30 cm. The flowers emerge on slender stems above the leaves, typically arranged in clusters of two to three at the top. Each flower features three prominent white outer petals, while the three inner petals tend to be more upright and are generally tinted.
