Grevillea rosmarinifolia, the rosemary grevillea, is a plant of the family Proteaceae.

Description[edit]

Grevillea rosmarinifolia usually occurs as a small to medium sized shrub 0.3–2 m (0.98–6.56 ft) high. The greater size is achieved in milder districts.[2]

The leaves resemble rosemary - narrow-linear, stiff with sharp points and curled-under margins, 0.8-3.8 cm long and 0.7–3 mm wide.[3]

G. rosmarinifolia produces clusters of red or pink flowers from winter to spring.[2] The flowers are rich in nectar and attract nectarivorous insects and birds.

Taxonomy[edit]

It was first described by Allan Cunningham, an English botanist on an expedition in New South Wales. There are two currently recognised subspecies:[4]

  • G. rosmarinifolia subsp. glabella(R.Br.) Makinson
  • G. rosmarinifolia A.Cunn. subsp.rosmarinifolia

Distribution and habitat[edit]

It is native to New South Wales and Victoria, Australia, and has naturalised in South Australia.

G. rosmarinifolia prefers full sun. It is drought tolerant and hardy down to −10 °C (14 °F).[5]

Grevillea rosmarinifolia is cultivated as an ornamental plant, for use in gardens and drought tolerant landscaping. In the UK it has gained the Royal Horticultural Society’s Award of Garden Merit.[5][6]
