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 in autumn or spring. Grafted onto G. 'Poorinda Royal Mantle' or G. robusta root stock.

This plant is resistant to Phytophthora cinnamomi and contact with the foliage may cause skin allergies.

Note:
The species is not commonly cultivated though grafted forms are found in the humid eastern Australian states but may be difficult to obtained, requiring a specialist nursery.

Botanic information
Leaf: The almost sessile leaves are deeply pinnatisect with 5 to 15 linear lobes that are up to 135mm (5¼in) long. The texture is leathery and the underside is silvery with silky hairs.

Flower: The small tubulate flowers have villous perianth segments that are yellow-grey and an exserted black style that is up to 20mm (¾in) long and is curved becoming straight with age. The flowers are arranged in a one sided axillary raceme that is up to 80mm (3⅛in) long and appear from early spring to early summer. 

Fruit: The oblong follicle is up to 9mm (⅜in) wide with a thin tomentose pericarp and contain smooth oblong seeds to 12mm (½in) long. The small seeds are viable but the plant is normally reproduced vegetatively.
Woody follicle is persistent and contains 2-winged 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.
