Propagation
Sow fresh seed during early spring and pre-soak seeds in heated water 13º to 18ºC (55º-64ºF) for 24 hours. Seeds require scarification (peeling treatment).

Soft wood cuttings taken from spring to summer and apply bottom heat. Cuttings may be very difficult to strike but the plan has been successfully grafted onto Grevillea robusta.

Botanic information
Leaf: The stiff leathery textured concolorous ovate-obovate to spathulate leaves are up to 90 mm (3½ in) long by 55 mm (2⅛ in) wide and have a pungent acute apex. The variable margins are undulate to entire but more commonly dentate with 2-7 triangular pungent teeth.

Flower: The tubulate flowers have a pedestal up to 9 mm (⅜ in) long and the strongly curved oblong to oblong-ovoid yellow to cream or red 4-parted perianth segments are up to 7 mm (¼ in) long by 4 mm (⅛ in) wide with a protruding yellow pistil to 10 mm (⅜ in) long with a lateral pollen presenter. They are glabrous or glandular hairy on the outside and villous inside. The flowers are arranged in a decurved cylindrical, normally axillary, villous raceme up to 100 mm (4 in) long by 30 mm (1⅛ in) wide and are accompanied by deciduous ovate bracts up to 3 mm (⅛ in) long. The flowers appear from winter to early spring and appear sporadically throughout the year in warm regions.

Fruit: The oblong-ellipsoidal follicle is up to 20 mm (¾ in) wide by 15 mm (⅔ in) wide with a glaucous glabrous pericarp. The smooth ellipsoidal seeds are up to 8 mm (⅓ in) long by 4 mm (⅛ in) wide and surrounded by a membranous wing. The small seeds are viable but the plant can be reproduced vegetatively with some difficulty.
