Johnson's Grevillea

Grevillea johnsonii (Johnson's grevillea) is a shrub species which is endemic to New South Wales in Australia.

It grows to between 2 and 4.5 metres high. The leaves are 10 to 25 cm long and have narrow lobes that are 0.7 to 1.5 mm wide. Flowers appear between August and November (late winter to late spring) in the species' native range. These have red to orange perianths and styles. Grevillea johnsonii mainly occurs in the Goulburn and Capertee River catchments.

Intriguing evergreen, rosemary-like foliage makes a stunning impact, especially in the spring and early summer when smothered in clusters of red and orange spidery blooms. In fact, if planted in a sheltered site, the blooms will appear almost all year round. Attractive to birds and drought tolerant. Prefer well-drained soil in sun or part shade. Height & spread 2.7m (9'). Hardy grafted perennials to around -7 C.
