A shrub growing potentially to 3 x 3 metres or more wide but can be kept shorter through pruning.
It is a hybrid between G. pinaster and G. olivacea (two Western Australian species). Its origins have not been determined for this profile.
Leaves are light to dark green, strongly divided into linear segments (forking pattern), to about 8 cm long and 4 cm wide, with narrow linear segments to 0.5 cm across.
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 spider racemes, with inflorescences to about 5 cm long by 8 cm wide. They are a mixture of red-pink-orange and golden-yellow / deep-cream with hints of green. Flower are produced mainly in winter and spring.
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. In this cultivar, the carpels are to 40 mm long, deep pink-red-orange with yellow tips. The perianths are deep-cream / gold on green stalks.
A very attractive grevillea. It can be observed on some websites growing well overseas.
It is a nice plant just for the foliage but the inflorescence colour is a major attraction.
Works well as a feature plant, as a stand-alone in a lawn or other landscape but can also be integrated with other plants. Tolerates a range of soils, so long as drainage is adequate and will grow in a wide range of and is reportedly good in cool climates. Plant in full sun or part shade.
Prune lightly to shape and encourage flowering as well as to control its form. Plants can get too large if not pruned correctly.
Must be propagated by cuttings to retain “true-to-form” type. 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 is a diverse genus of about 360 species of evergreen flowering plants native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. NSW currently has about 85 species although with a lot of subspecies and some informal taxa recognised.
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.
