Grevillea rosmarinifolia
Rosemary Grevillea

Located in the Australian section of the International Garden, this native of southeastern Australia forms a small, evergreen shrub growing to four feet tall with narrow, stiff rosemary-like leaves. Clusters of pink or red flowers occur in the early spring and have interesting petals that curl like snail shells. Rosemary Grevillea prefers full sun and is quite drought tolerant once established. Grevillea is a member of the Proteaceae family, a plant family mainly restricted to the Southern Hemisphere. Another Grevillea growing in the International Garden is Grevillea robusta, commonly known as Silk Oak. This species has grown to over twenty feet tall but has yet to flower.
