Plant description

Dense, prostrate to decumbent shrub to 90 cm across; young branches red-brown, older stems dark-brown to grey-brown with hairy branchlets. Leaves flat, linear-lanceolate to lanceolate, to 13 mm long and 2.5 mm wide, sparsely hairy on both surfaces; lower surface with 3–7 unbranched subparallel veins; margins serrated. Inflorescence in a small spike with 5–12 tubular flowers with corolla sometimes maroon-tinged; tube transluscent, lobes green. Flowering between August and September. Fruits are flattened spherical fruit to 3.5 mm long and 4.5 mm wide, greenish but turning whitish as it mature; scarcely succulent. Seed embryo type is linear underdeveloped.

Seed collection and propagation

Collect seeds between October and February. Lift branches carefully to locate the fruits. Collect berries that are turning creamy white and soft with a hard seed inside. Place the berries in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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.
