Discussion

In its native range, Dianella ensifolia occurs in a broad ecological range, from seashores, grasslands, and open scrubs to alpine and open lowland forests between sea level and 1600 m. In Florida, this naturalized ornamental probably spreads by its extensive rhizome systems and colorful fruits (W. B. Zomlefer 1998).
