Plant description

Low erect shrub to 1 m high with a reddish-brown hairs on young branches. Leaves narrowly elliptic-oblong, to 5 cm long and 1 cm wide, dark-green, glabrous above and hairy reddish-brown on the lower surface. Inflorescence solitary more or less erect on short axillary branchlets, with an erect narrow tubular pink-red with yellow-green tips flower. Flowering between November and February. Fruits are brown capsule to 10 mm long, enclose by the sepals. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between January and March. Collect mature capsules, those that are turning a pale straw colour and contain hard seeds, either by hands or place small breathable bags over immature capsules to collect seed. Capsules maybe hard to see as it is enclose by the sepals. Place the capsules in a tray and leave to dry for a weeks. Then rub the capsules gently by hand to dislodge the seeds. Be very careful as the seed coat is thin and easily damaged. Use a sieve to separate the 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. This species has morphophysiological dormancy and can be difficult to germinate.
