Etymology

Dianella is a diminutive of Diana, the virginal Roman goddess of hunting and the moon. The original species named was found located in the French woods, thus the hunting association. Brevicaulis from the Latin 'brevis' meaning short and 'caulis' meaning a stem, referring to the flower-spike being shorter than the foliage only 3/4 the length)

Plant description

Closely tufted perennial lily to 50 cm tall. Leaves to 85 cm long; not glaucous, usually dark yellow-green. Flower-spikes with spreading branches much shorter than the foliage, with 2–9 mid to dark blue or violet flowers. Stamens yellow and anthers pale brown to almost black. Flowering between October and December. Fruits are round blue berries containing numerous seeds. Seeds are shiny black ovoid seeds to 4 mm long and 2 mm wide. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between November and February. Pick the fruits that are soft and purple. These will have hard black seeds inside. It is best to clean the fruit when it is fresh. Place fruits in a bucket of water and rub the fruit gently by hand to dislodge the seeds. Then use a sieve to separate unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily.
