About

Grevillea spp.

The unusual and striking flowers of the Proteaceae family grow in the southern hemisphere countries of South America, South Africa, New Zealand and Australia, that once composed the huge continental mass of Gondwana. Plate tectonics over millions of years separated the various continents from each other, but the botanical family connections between them are still there, though the species differ vastly from each other. Captain Cook, the British explorer, named his first landing in Australia, “Botany Bay” for the exotic plants blooming on its shores. Sir Joseph Banks, his botanist on board, collected two dozen varieties of Grevilleas to be taken back to England. The genus was subsequently named after Charles Francis Greville, who was one of the founders of the Royal Horticultural Society.

Most Grevilleas are endemic (growing nowhere else) to Australia with more than 300 different named species. G. robusta is a 90 foot tree with orange blooms. Another, G. aquifolium, is a ground cover with oak-like leaves. All require a hot dry mediterranean climate with winter rains and excellent drainage. California gardens needing drought tolerant plants can do well with the great variety of grevilleas available.
