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 root quickly and care should be taken not to disturb the roots when potting up.

It is is resistant to Phytophthora cinnamomi and the foliage may cause skin irritations so care should be taken when pruning. 

Botanic information
Leaf: The leaves are deeply pinnatisect with 9 to 11 lanceolate lobes up to 15mm (⅝in) long. The upper surface is covered in a fine silky hairs and underside is silvery-villous with a prominent mid-vein. The petiole is short and the margins are recurved. 

Flower: The small tubulate flower has a pedicle up to 10mm (⅜in) long with villous oblong perianth segments, 4-stamens and a style to 50mm (2in) long that is hooked at the pollen presenter. The flowers are arranged in a cylindrical terminal raceme that is up to 120mm (4¾in) long and appears from spring to early summer.

Fruit: The sessile ovoid follicle is up to 10mm (⅜in) wide with a thin tomentose pericarp. The oblong seeds are up to 12mm (½in) long with a wing around the margin. The small seeds are viable but the plant is normally reproduced vegetatively.
The capsule is woody, splitting to release one to two seeds.

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 acidic sandy 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.
