Descriptions of Registered Cultivars
ORIGIN: Grevillea 'Crimson Glory' arose as a chance seedling on the property of Mr P Baker of Coldstream, Victoria. It appeared amongst stock plants in a very large Grevillea plantation. The possible parentage is G. acanthifolia x G. willisii. The name refers to the flower colour. The cultivar was first received by the Authority in May 1984. Registration applied for by Mr P Baker of Coldstream, Victoria.
DESCRIPTION: Grevillea 'Crimson Glory' grows to around .3m tall by up to 1.5m wide and is very densely branched. The leaves are up to 80mm long by 45mm wide. They are deeply and fairly regularly lobed, and each lobe terminates in a sharp tip. The leaf margins are thickened but not recurved or rolled under. The veins are light coloured and are easily visible above though are not markedly raised. They are prominent on the underside of the leaf. The upper surface of the leaf is almost glabrous, with some scattered silky hairs along the main vein of the leaf. The underside of the leaf is covered with a dense mat of closely appressed silky hairs. The flowers are of the "toothbrush" type and are terminal on short lateral branchlets. The perianth segments are pale in colour and densley hairy. The style is crimson and glabrous. Occasional flowers are found throughout the year, with the main season being September to May.

CULTIVATION NOTES: The semi-prostrate growth and long flowering period make this a worthwhile garden plant. It has been grown in Victoria and has proved hardy in most situations. It has withstood temperatures down to -5 degrees C and does well in heavy soils with little supplementary watering. The cultivar must be propagated by vegetative means to preserve the cultivar form.
