ORIGIN: Grevillea 'Poorinda Empress' is said to be a hybrid between Grevillea hookerana and Grevillea caleyi. Cultivar received by the Authority: 21st October 1975. Applicant Mr. L. Hodge.
DESCRIPTION: It is a large compact shrub growing to a height of 3-4m. The leaves are extremely deeply lobed and about 120mm long by about 55mm wide across the lobes. Individual lobes are pungent and narrow being about 3mm wide. The upper leaf surface is dark shiny green whilst the underside is covered with dense silky hairs. The edges of the lobes are rolled under. The flowers are of the "toothbrush" type and are borne terminally on branchlets and occasionally on the main stem opposite a leaf. The perianth is red to purple and 10-12mm long and the deep pink styles about 30mm long.
DIAGNOSIS: This cultivar is different from its stated parents in width and shape of the leaf lobes. Grevillea 'Poorinda Empress' has wider lobes than Grevillea hookerana but narrower lobes than Grevillea caleyi which has distinctly rounded lobes. The styles are the same colour as Grevillea caleyi but darker than Grevillea hookerana.
