General Description

The genus Dianella is made up of 25 species of woodland plants. These originate from tropical Africa, Asia, Australia, and Polynesia. The genus is named for the Roman goddess of the hunt and forest, Diana.

Most Dianella are evergreen herbaceous perennials borne from thick underground stems that grow laterally. They spread to form clumps or colonies. Most have upright grassy foliage consisting of strap-like or lance-shaped blades. These range in color from deep green to blue-green or pale green with or without variegation. Sometimes the foliage is equitant, which means it’s arranged in flattened fans.

The flowers are lily-like, small and often appear on tall branched leafless stems. Each small flower is nodding or upward-facing with petals that curve back to show a flare of bright yellow male structures called stamens. These are followed by persistent berry-like fruits that are round to oblong and blue or violet.

Cultural requirements vary somewhat among species, but most prefer full sun to partial shade and soils with good drainage. They can be grown outside in mild climates and in containers in colder zones. Dianella will tolerate some frost and is drought tolerant once established though it looks best if watered during dry spells.

Popular species include the Australian Dianella caerulea (Paroo lily), which has weeping, strap-like foliage and blue flowers. Dianella ensifolia (umbrella dracaena) has very upright stalked stemswith lavender blue flowers and Dianella tasmanica (blueberry flax lily) spreads and is planted as a groundcover.
