'''''Grevillea''''' ({{pron-en|ɡrɨˈvɪliə}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a diverse [[genus]] of about 360 species of [[evergreen]] [[flowering plant]]s in the protea family [[Proteaceae]], native to [[Australia]], [[New Guinea]], [[New Caledonia]], and [[Sulawesi]]. It was named in honour of [[Charles Francis Greville]]. The species range from [[prostrate shrub|prostrate]] [[shrub]]s less than 0.5 m tall to [[tree]]s 35 m tall. Common names include '''Grevillea''', '''Spider Flower''', '''Silky-oak''' and '''Toothbrush'''.
 +
 +
Closely related to the genus ''[[Hakea]]'', the genus gives its name to the subfamily [[Grevilleoideae]]. Many species of grevilleas are popular [[garden plant]]s, especially in Australia but also in other temperate and subtropical climates. Many grevilleas have a propensity to interbreed freely, and extensive hybridisation and selection of horticulturally desirable attributes has led to the commercial release of many [[cultivar]]s. Among the best known are [[Grevillea 'Robyn Gordon'|''Grevillea'' 'Robyn Gordon']], a small shrub up to 1.5 metres high and wide which can flower 12 months of the year in subtropical climates.
 +
 +
Many species are cultivated for their distinctive foliage and showy [[flower]]s, and they have been extensively [[Hybrid (biology)|hybridised]].
 +
 +
Grevilleas hybridise extremely easily in cultivation. this has resulted in a huge number of named [[Grevillea cultivars]].
 +
 +
They are also good bird-attracting plants, honeyeaters in particular are common visitors.
 +

==Cultivation==
 +
  
−
Grevillea (Charles F. Greville, once vice-president of the Royal Society of England, and a patron of botany). Proteaceae. Trees and shrubs, of about 200 species, mostly Australian, one of which is commonly cultivated in this country as a decorative pot-plant and also in the open in southern California and elsewhere in warm regions.
+
===Propagation===
 +
They can be grown from soft tip [[cutting]]s from December-March (in the [[Southern Hemisphere]]) or [[seed]].  
  
−
Leaves alternate, very various: fls. small, perfect, mostly in pairs in the clusters or racemes, apetalous, the calyx with 4 recurved parts; stamens of 4 sessile perfect anthers borne on the sepals; style 1, long and curved: fr. a follicle, with 1 or 2 winged orbicular or oblong flat seeds. The fls., sometimes showy and ornamental, are terminal and axillary, the racemes sometimes umbel-like. The fls. of some species produce honey. Some species yield useful timber.
+
Many harder to grow species can be grafted onto hardy rootstock such as ''[[Grevillea robusta]]''.

Grevillea flowers were a traditional favourite among Aborigines 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 (pronounced /ɡrɨˈvɪliə/)[1] is a diverse genus of about 360 species of evergreen flowering plants in the protea family Proteaceae, native to Australia, New Guinea, New Caledonia, and Sulawesi. It was named in honour of Charles Francis Greville. The species range from prostrate shrubs less than 0.5 m tall to trees 35 m tall. Common names include Grevillea, Spider Flower, Silky-oak and Toothbrush.

Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae. Many species of grevilleas are popular garden plants, especially in Australia but also in other temperate and subtropical climates. Many grevilleas have a propensity to interbreed freely, and extensive hybridisation and selection of horticulturally desirable attributes has led to the commercial release of many cultivars. Among the best known are Grevillea 'Robyn Gordon', a small shrub up to 1.5 metres high and wide which can flower 12 months of the year in subtropical climates.

Many species are cultivated for their distinctive foliage and showy flowers, and they have been extensively hybridised.

Grevilleas hybridise extremely easily in cultivation. this has resulted in a huge number of named Grevillea cultivars.

They are also good bird-attracting plants, honeyeaters in particular are common visitors.

Cultivation

Propagation

They can be grown from soft tip cuttings from December-March (in the Southern Hemisphere) or seed.

Many harder to grow species can be grafted onto hardy rootstock such as Grevillea robusta.
