Grevillea, Plant of the Month

Grevillea cv. 'Robyn Gordon', Australia (credit: SWP Media)

Australia has a rich heritage of indigenous plants stretching back to the era of ancient Gondwanaland. This plant biodiversity offers many choices that could easily be a 'plant of the month' candidate.

The vast continent is rich in members of the Protea family (Proteaceae), named for the Greek god Proteus who could easily change his form. In Australia, this large family of native plants includes species of Hakea, Banksia, Isopogon, and Grevillea and many are restricted in distribution---sometimes known from only a single mountain top. Grevilleas are indigenous to Australia with over 350 species known so far. The flowerhead typically has the individual flowers arranged in a loose radiating bundle of stamens to attract pollinators, particularly Australian birds. Two species were seen growing in Western Australia where some of the most endemic species exist.

An excellent book covering 2000 native Australian plants and trees is: The Definitive Guide to Australian Plants. Grevilleas are a worth group for Plant of the Month.
