'''''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== ===Propagation=== They can be grown from soft tip [[cutting]]s from December-March (in the [[Southern Hemisphere]]) or [[seed]]. Many harder to grow species can be grafted onto hardy rootstock such as ''[[Grevillea robusta]]''. ===Pests and diseases=== ==Species== {{Main|List of Grevillea species}} There are over 350 species which are [[endemic (ecology)|endemic]] to Australia, including the following: {| |- valign=top | * ''[[Grevillea acanthifolia]]'' [[Allan Cunningham (botanist)|A.Cunn]]. * ''[[Grevillea alpina]]'' [[John Lindley|Lindl.]] * ''[[Grevillea annulifera]]'' [[Ferdinand von Mueller|F.Muell.]] * ''[[Grevillea aquifolium]]'' [[John Lindley|Lindl.]] * ''[[Grevillea arenaria]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea argyrophylla]]'' [[Carl Meissner|Meisn.]] * ''[[Grevillea armigera]]'' [[Carl Meissner|Meisn.]] * ''[[Grevillea asparagoides]] [[Carl Meissner|Meisn.]] * ''[[Grevillea aspera]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea aspleniifolia]]'' Knight * ''[[Grevillea australis]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea banksii]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea barklyana]]'' [[Ferdinand von Mueller|F.Muell.]] ex [[George Bentham|Benth.]] * ''[[Grevillea baueri]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea beadleana]]''<ref>[http://www.threatenedspecies.environment.nsw.gov.au/tsprofile/profile.aspx?id=10360 Threatened species]</ref> * ''[[Grevillea bedggoodiana]]'' [[J.H.Willis]] ex [[McGill.]] * ''[[Grevillea bipinnatifida]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea brachystylis]]'' [[Carl Meissner|Meisn.]] * ''[[Grevillea bracteosa]]'' [[Carl Meissner|Meisn.]] * ''[[Grevillea buxifolia]]'' ([[James Edward Smith|Sm.]]) [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea bronwenae]]'' [[Keighery]] * ''[[Grevillea caleyi]]'' [[Robert Brown (botanist)|R.Br.]] * ''[[Grevillea candelabroides]]'' [[Charles Gardner|C.A.Gardner]] * ''[[Grevillea candicans]]'' [[Charles Gardner|C.A.Gardner]] * ''[[Grevillea celata]]'' [[Bill Molyneux|Molyneux]] * ''[[Grevillea centristigma]]'' ([[Donald McGillivray|McGill]].)
