Propagation
Take semi hardwood cuttings from summer to winter.

This plant is resistantto Phytophthora cinnamomiand the foliage may cause skin irritations so care should be taken when pruning.


Botanic information
Leaf: The sub-sessile linear-lanceolate leaves have a sharp-pointed apex and recurved margins. The upper surface is dark green and the pale green underside is pubescent.

Flower: The tubulate flowers have pink and cream to lemon-green or orange perianth segments with a red style that is looped then becoming straight. The flowers are arranged in an umbellate raceme that appears in the upper leaf axils during spring.

Fruit: The woody boat-shaped follicle has a persistent style and contains two winged seeds. 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 treeswith a large range of foliage types and are usually bird attracting.

The inflorescencesrange from globular heads that may be elongated to toothbrush-like one sided raceme.
The individual flowersconsist 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 ripeand sticky ready for another visitor todeposit pollen, which will grow and induce fertilisation.

Thefruitis 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 arenormally grown from semi-hardwood cuttings that producesensitive 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.
