Tough and adaptable, this evergreen shrub can eventually reach 6-8' tall with similar spread.

Best on the west coast, but it tolerates the heat and humidity of the southeastern US, too. A nice specimen grows in the Armstrong Atlantic State University Arboretum in Savannah, Georgia.

Flowers most heavily in spring, then blooms sporadically the rest of the season.

Needs good drainage. Tolerates drought, but best with lots of water in summer and kept drier in winter. Phosphorus fertilizer is toxic to this plant (and many other Australian plants).

This is a hybrid, Grevillea juniperina x G. rosmarinifolia.

Long blooming showy flowers in winter. In Portland, OR it must be
grown in a very protected location to last more than 5-6 years. Hardy
to 12- very damaged below that.
