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
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. 
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:
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).
