Grevillea
Evergreen shrubs and trees with distinctive spider-like flowers
Grevillea is a genus of about 360 evergreen shrubs and small trees, mostly native to Australia, with a few species in New Guinea, New Caledonia, and Sulawesi. Known for their unique, often brightly coloured flowers, grevilleas attract birds and insects, are popular in gardens, and have traditional uses among Aboriginal Australians.

What does Grevillea look like?
Grevillea plants are mostly evergreen shrubs, though some grow as small trees. Their leaves can be simple or divided and are arranged alternately along the branches. The flowers are often described as spider-like, with long, curved styles and are grouped in racemes at the ends of branches. Flower colours vary widely, from white and cream to yellow, pink, and bright red. Some species have fragrant flowers, especially those pollinated by insects. The fruit is a thin-walled pod that splits open on one side to release one or two seeds.
Where does Grevillea come from?
Most grevillea species are native to Australia, where they grow in a range of habitats except for alpine, swampy, or saline areas. A few species are found in New Guinea, New Caledonia, and Sulawesi. The genus was formally described in 1809 and named after Charles Francis Greville, a British botanist and co-founder of the Royal Horticultural Society. Grevilleas have been introduced to other countries, sometimes becoming invasive, especially Grevillea robusta.
When and how Grevillea blooms
Grevilleas flower at different times depending on the species and climate, with some able to bloom year-round in subtropical regions. They are commonly grown from seed or soft tip cuttings, and some difficult species are grafted onto hardy rootstocks. In gardens, they are valued for their nectar-rich flowers and ability to attract birds. Cultivars have been developed for horticulture, with some, like 'Robyn Gordon', flowering nearly all year.
How Grevillea is used
Grevilleas are widely grown as ornamental plants in gardens, especially in Australia. Aboriginal Australians have traditionally used the nectar from certain species as a sweet treat, either by sucking the flowers or soaking them in water. Some species' seeds are also eaten. The wood has been used for furniture. However, some grevilleas are toxic and can cause skin irritation or allergic reactions.
Kinds of Grevillea
There are over 380 species in the genus, with most found only in Australia. Notable species include Grevillea robusta (silky oak), which is widely planted and sometimes invasive, and Grevillea banksii, popular in cultivation. Many hybrids and cultivars exist, such as 'Robyn Gordon' and 'Canberra Gem'. Some species are critically endangered due to habitat loss.
What Grevillea means
Grevilleas are important in Australian gardens and are a food source for native birds and insects. They hold cultural significance for Aboriginal Australians, who use them for food and ceremonial purposes. Conservation is a concern, with many species listed as threatened. The genus is named in honour of Charles Francis Greville.
