Perennial shrubs to 1.3 m high, usually little-branched; glutinous, densely covered with short forward-directed appressed hairs on the stems, soon wearing off. Leaves leathery with a recurved margin with few fine hairs above and densely hairy below; obtuse to rounded, oblong-elliptic rarely oblong-lanceolate,to 25 mm long and 7 mm. Inflorescence terminal with 1-5 clusters each with 1-3 deep-blue flowers. Flowering between August and October. Fruits are fruit indehiscent drupe, usually with 1 seed.

Seed collection and propagation

Collect seeds between November and December. Collect fruits that are maturing, fat and hard. Place the fruits in a tray and leave to dry for two weeks. Then rub the fruit gently to dislodge the seeds. 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.
