Grevillea rosmarinifolia (Rosemary Grevillea)
Grevillea rosmarinifolia is a dense and bushy evergreen shrub of loose, arching, graceful habit with rosemary-like leaves which contrast nicely with the red spidery flowers. Reminiscent of the culinary rosemary, the foliage is linear, glossy, dark green on top and downy silvery underneath, to 2 in. long (5 cm). Borne in dense terminal clusters, deep rose-red flowers are produced in pairs along the branches from late winter through to late summer, and occasionally at other times. They open in succession from curling buds, the curled part of the flowers straightening out to make the spider legs. These spectacular and unique flowers are full of nectar and attract birds, bees and insects to your garden. This plant is tolerant of heat, drought and wind everywhere except in hot, low desert climates.
