Etymology

Dianella is a diminutive of Diana, the virginal Roman goddess of hunting and the moon. The first-named species was found located in the French woods, thus the hunting association. Longifolia from Latin meaning long leaves. Grandis from Latin meaning large, tall or lofty, alluding to the large flower-spike.

Distribution and status

The taxonomy of the Dianella longifolia group is under revision and the distribution will change. It was previously recorded from the southern Flinders Ranges, Mount Lofty Ranges and the South-east in South Australia, growing in grassy woodland and was also recorded from Queensland, New South wales and Victoria. The taxonomy of the Dianella longifolia group is under revision and the status will change. It was previously considered rare in South Australia, Queensland and New South Wales and Uncommon in Victoria.

Plant description

The taxonomy of the Dianella longifolia group is under revision and the description will change. It was previously described as a perennial herb to 1 m high. Leaves mostly basal, pale blue-green, forming loose clumps to 60 cm high; flower-spike a panicle with pale blue flowers and much longer than the foliage. Anthers yellow.Flowering between September and January. Fruits are round deep-blue to purple berries containing numerous seeds. Seeds are shiny black ovoid seeds to 4 mm long and 3 mm wide. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between November and March. 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 seven collections, the seed viability was low to high, ranging from 40% to 100%. Seeds are non-dormant, viable seed should germinate readily.
