Name derivation:
Viminaria from the Latin 'vimen' meaning twiggy; referring to the long twiggy leafless branches. Juncea from the Latin 'juncus' meaning rush-like; alluding to its leafless appearance
Distribution:
Found on Kangaroo Island, the southern Mount Lofty Ranges and the lower South-east in South Australia, growing in swampy depressions in heathland or woodland. Also found in all other states except in the Northern Territory. 
Status:
Native. Rare in South Australia. Very rare in Tasmania. Common in the other states.
Plant description:
Shrub to 5 m high with pendulous, wiry, glabrous, green and striate branches. Juvenile leaves 1–3-foliolate, leaflets oblong to linear-lanceolate, to 4 cm long,  mature leaves reduced to slender petioles to 25 cm long. Flowers in racemes to 20 cm long with yellow to orange often with red blotches pea-flowers. Flowering between November and February.
Fruit type:
Black ovoid pod to 5 mm long, with one seed inside.
Seed type:
Mottled orange-red, reniform seed to 2.5 mm long and 2 mm wide.
Embryo type:
Bent.
Seed collecting:
Collect maturing pods, those that are fat, turning black and contain a hard orange seed inside, by running your hands along the fruit-spikes.
Seed cleaning:
Place the pods in a tray and leave to dry for 1 to 2 weeks. Then rub the dried pods to dislodge the seeds. Use a sieve to separate any 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.
Seed viability:
From two collections, the seed viability were high, at 100%.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
