Description

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]

Grevillea 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.

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

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

Distribution and habitat

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

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

Cultivation

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]
