Grevillea laurifolia, commonly known as laurel-leaf grevillea,
Description
Grevillea laurifolia is a prostrate, trailing shrub that can attain a diameter of 4.5 m (15 ft). Its leaves are egg-shaped to elliptic, sometimes heart-shaped or round, 25–160 mm (0.98–6.30 in) long and 25–60 mm (0.98–2.36 in) wide on a petiole 6–28 mm (0.24–1.10 in) long. The leaves sometimes have wavy edges, and the lower surface is silky-hairy. The flowers are arranged on one side of a rachis 20–80 mm (0.79–3.15 in) long and are reddish to deep maroon, the style with a green to yellow tip, and the pistil 13–25 mm (0.51–0.98 in) long. Flowering mainly occurs from September to January with a peak in November, and the fruit is a woolly-hairy follicle 9.0–9.5 mm (0.35–0.37 in) long.[2][3][4][5]
Taxonomy
Grevillea laurifolia was first formally described in 1827 by Kurt Polycarp Joachim Sprengel in Systema Vegetabilium from an unpublished manuscript by Franz Sieber.[6] The specific epithet (laurifolia) means having leaves similar to species of Laurus.[7]
In 2015, Peter M. Olde described two subspecies of G. laurifolia in the journal Telopea, and the names are accepted by the Australian Plant Census:
- Grevillea laurifolia subsp. caleyana Olde[8] has leaves with an average blade length to width ratio more than 2.2:1, the pistils 9.5–14 mm (0.37–0.55 in) long.[5]
- Grevillea laurifolia Sieber ex Spreng. subsp. laurifolia[9] has leaves with an average blade length to width ratio less than 2.2:1, the pistils 17–25 mm (0.67–0.98 in) long.[5]

Use in horticulture
Grevillea laurifolia adapts readily to cultivation provided it has good drainage and a sunny aspect. It can have difficulties at lower altitudes.[7] Larger-leaved forms have been selected for horticulture and make attractive groundcover plants and can attract birds to the garden.[10] Grevillea 'Poorinda Royal Mantle' is a vigorous cultivar that was bred by Victorian plantsman Leo Hodge and registered in 1978; it is thought to be a hybrid between G. laurifolia and G willisii.[11] The most commonly cultivated subspecies is subsp. caleyana, because of its larger flowers.[5]
