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

Take semi-hardwood cuttings during summer and apply bottom heat.

Culture
In eastern states of Australia grafted forms are available.

Botanic information
Leaf: The broad elliptical to obovate papery textured leaves have a mucronate apex and a short petiole. The margin is densely pubescent and the leaf underside is glabrous. 

Flower: The small tubulate flowers have a pedestal up to 4 mm (⅛ in) long and the oblong yellow to orange perianth segments are up to 9mm (⅜ in) in length with a yellow pistil to 8mm (⅓ in) long, that doesn't exceed the perianth segments. There are up to 18 flowers are arranged in a terminal or sometimes axillary, villous raceme that is accompanied by ovate bracts up to 4 mm ⅛ long. The flowers appear from late winter to early summer and are pollinated by birds.

Fruit: The almost glabrous ovoid follicle is up to 7mm (¼ in) wide with a reddish-brown ribbed pericarp and contains a single oblong seed to 9mm (⅜ in) long. The small seeds are viable but the plant is normally reproduced vegetatively.

Grevillea Species
A majority of this genus is endemic to Australia with a larger proportion found in south-western Western Australia. 
They consist of prostrate shrubs, shrubs and trees with a large range of foliage types and are usually bird attracting. 

The inflorescences range from globular heads that may be elongated to toothbrush-like one sided raceme.
The individual flowers consist of a perianth tube that is made up of four segments that are fused except for one side. There are four stamens that are arranged at the tip of the perianth tube and a long hooked style.

Pollination mechanism
Ripe pollen is shed onto the unripe stigma where visitors pick it up. When the pollen is removed or it dries up the stigma becomes ripe and sticky ready for another visitor to deposit pollen, which will grow and induce fertilisation.

The fruit is a capsule (follicle) and is normally leathery splitting to release one or two winged seeds.

Propagation
Although the seeds are viable seedling stock can vary from the parent plant. Grevilleas are normally grown from semi-hardwood cuttings that produce sensitive roots. Care should be taken when potting up or planting out. 
Plants derived from cuttings are busher than seedling stock.

Soils
Grevilleas will tolerate most soil types though they tend to prefer slightly acid or clay soil types that are well drained.

Aspect
Grevilleas will grow in full sun to shade positions though flower production will diminish in shade. They can tolerate dry periods and some tolerate frost, most of the genus is hardy and tolerate neglect.
