A shrub that grows to 5 metres high by 4 wide. The cultivar is very similar to G. banksii which is one of the original parents. It is thought this cultivar is a progeny of Grevillea ‘Pink Surprise’.
It has deep green, attractive, deeply divided leaves to 12 centimetres long by 7 centimetres in width. The foliage takes on a bronze sheen in winter, especially the new growth.
A grevillea inflorescence is technically a cluster of paired flowers, termed a conflorescence with the overall structure forming a raceme-like appearance.
Grevillea species exhibit 3 main inflorescence structures:
1. A cylindrical to ovoid raceme (with flowers emerging around a 360° radius)
2. A single-sided raceme (with flowers produced on only one side, resembling a tooth-brush)
3. A condensed or clustered raceme (usually as long as it is wide, with species referred to as the spider-flowers)
Grevillea mostly produce the inflorescences at the terminals, beyond the foliage, which differs to the closely related Hakea.
This cultivar has a cylindrical raceme, with inflorescences to about 15 centimetres long by 9 centimetres wide. They are deep pink-red and very showy.
Individual flowers are composed of 1 carpel (female part) where the style and stigma protrude out; 4 stamens hidden away in the perianth; and the perianth (petals and sepals collectively) which connects to a pedicel. Proteaceae flowers do not have any discernible petals or sepals (having only one whorl) and so these are referred to as “tepals” of which there are 4. The carpels are to 40 mm long, pink with yellow tips.
A very attractive plant for a garden situation with well-drained soil and full sun.
It is reportedly a very fast growing and hardy shrub. It tolerates a range of soils and can cope without supplementary watering, although plants will flower much more heavily if watered. Can tolerate hard pruning where plants that may be several metres tall can be cut back to about 1 m tall to refresh the plant and provide new dense growth.
Although not yet recorded, the cultivar is very similar to several cultivars which have been known to cause allergic contact dermatitis for certain individuals who come into contact with it, so caution is advised. Very good cut flower, harvest when the inflorescence is in bud rather than full-flowered. The inflorescences are of a good large size and are produced over much of the year.
Grevilleas are propagated by three principal methods; seed, cuttings and grafting. To maintain desirable characteristics of a particular plant, vegetative propagation (e.g. cuttings or grafting) must be used. This also applies to propagation of named cultivars.
Grevillea flowers were a traditional favourite among First Nations Peoples for their sweet nectar. This could be shaken onto the hand to enjoy, or into a coolamon with a little water to make a sweet drink. They might be referred to as the original “bush lollies”.
Grevillea – was named in honour of Charles Francis Greville (1749-1809), an 18th century patron of botany and co-founder of the Royal Horticultural Society. He was also a British antiquarian, collector and politician who sat in the House of Commons from 1774 to 1790.
‘Sylvia’ – origin of name uncertain.
