Grevilleas are a very diverse group of plants. They are diverse in how they look, and also in where they can be grown. They include trees, shrubs and ground covers. Foliage colour can be just as variable.
I've seen Grevilleas growing well in England and France; Japan and California; and many other places. Mostly though, they are widely grown across Australia. Some grow well in tropical rainforests, others in cold mountains that can be covered by snow for months of the year. Some species grow in deserts and others on the sea shore.
The foliage varies from tiny needle like leaves to large broad leaves, and the flowers from inconspicuous small cream flowers to large bunches of very colourful flowers that completely obscure the foliage.
