Grevillea

Grevillea
A massive genus of close to 340 species of trees and shrubs that are native to only Australia and less often New Caledonia. They are part of the Proteaceae family which also includes Banksias, Hakeas and Proteas among other genera.
Most species do not like organic compost or phosphorous rich soil. They should absolutely NOT be fertilized with anything containing phosphorus or potassium as too much of either can kill. Pruning after flowering improves vigor.
They are deer resistant and most species can tolerate severe drought, many preferring dry summers. The flowers attract hummingbirds.
Phytophora rot is a severe problem on Mediterranean species that are overwatered during summer. It not only occurs in Australia but has been also found in places outside its native range such as Italy where it is cultivated.
