Grevillea is very fast growing and can live 50 to 65 years. This evergreen has a rugged look. It can grow to be over 100 feet (30 m.) tall, but most mature trees are around 50 to 80 feet (15-24 m.)

How long do grevilleas last?

Many of the small trees we love in our gardens are not long lived trees – the grevilleas and acacias are a case in point. Ten to fifteen years is a typical life span for acacias and maybe 20 or so for some of the grevilleas.

Are grevilleas short lived?

The genera that have probably contributed most to labelling native plants as being short-lived are Acacia (Wattles) and Grevillea. Acacias have around 1000 species and Grevilleas 260. Most of these are short-lived species but they also contain some long-lived species.
