Growing Grevilleas

Develop your ability to select and cultivate appropriate varieties of Grevilleas in different situations.

Grevilleas are a wide group of plants, all but seven species coming from Australia. They are widespread across Australia, occurring in both cool temperate, and hot tropical climates.

There are around 250 species. About half of these are native to the south west corner of Australia.

Known commonly as “Spider Flowers”; the Grevillea flower is more like a brush than a traditional flower. It has obscure petals, but is none the less very colourful. Flower colour varies greatly; and most hold their flowers for a long period.

Grevilleas include both small to very large plants (from prostrate ground covers, through small and medium shrubs up to large trees).

Their hardiness is variable according to species. The foliage is also variable ranging from small, entire leaves to lobed or pinnate leaves. All are arranged alternately on the stems and some have hairy undersurfaces.  Most have a medium to fast growth rate.
