The Grevillea banksii (Red Silky Oak), native to Australia, is an attractive ornamental shrub or small tree that boasts vibrant, colorful foliage. It typically grows to a height of 5-10 ft tall as a large shrub, or up to 10-20 ft as a small tree. The fluffy foliage is a bright reddish-bronze when new, then matures to a glossy dark green.

The Grevillea banksii is a hardy, sun-loving plant that does best in USDA zone 9-11. It enjoys a moderate amount of water and prefers full sun exposure. In hotter climates, it should receive some afternoon shade or be mulched regularly in summer to help keep its roots cool.

Come late spring, Grevillea banksii produces a profusion of flowers in shades of pink, crimson, and vinous. The blooms are followed by yellow and orange fruits, which are attractive to hummingbirds and butterflies.

In colder regions, it should be grown in a pot that can be moved indoors over winter. With a little extra love and attention, it can be grown as a garden hedge or even as a lovely container specimen that offers year round color.
