Grevillea laurifolia | |
Grevillea laurifolia, commonly known as laurel-leaf grevillea, [2] is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is a prostrate, trailing shrub with egg-shaped, heart-shaped or round leaves, and clusters of reddish to deep maroon flowers.
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]
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laurifolia was first formally described in 1827 by Kurt Polycarp Joachim Sprengel in Systema Vegetabilium from an unpublished manuscript by Franz Sieber.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:
Subspecies laurifolia occurs in the Blue Mountains between Valley Heights and Wentworth Falls at altitudes between 250 and 835 m (820 and 2,740 ft). Subspecies caleyana is found mainly in the upper Blue Mountains between Wentworth Falls, Lithgow, Mount Werong, Wombeyan Caves and Mittagong between about 500 and 1,000 m (1,600 and 3,300 ft) above sea level. [5] It grows in low-nutrient clay-, shale- and sand-based soils, either on ridges and slopes or in the vicinity of swampy areas. The habitat is open sclerophyll forest under such trees as silvertop ash Eucalyptus sieberi , Sydney peppermint ( E. piperita ), broad-leaved peppermint ( E. dives , brittle gum ( E. mannifera , red stringybark ( E. macrorhyncha ), brown barrel ( E. fastigata ) and alongside shrubs such as Mirbelia platyloboides , dense phyllota ( Phyllota squarrosa ), mountain geebung ( Persoonia chamaepitys ), myrtle geebung ( P. myrtilloides ) and stiff-leaf wattle ( Acacia obtusifolia ), or in more open woodland or heath associated with Faulconbridge mallee ash ( Eucalyptus burgessiana ), Blue Mountains mallee ash ( E. stricta ), scribbly gum ( E. sclerophylla ), and silver banksia ( Banksia marginata ). [4]
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]
