Descriptions of Registered Cultivars
ORIGIN: Grevillea 'Poorinda Peter' is said to be a hybrid between G. acanthifolia and G. longifolia. Cultivar received by the Authority on the 21 October 1975. Applicant is Mr Leo Hodge of 'Poorinda', Mt Lookout Road, Bairnsdale, Victoria.
DESCRIPTION: This cultivar is a large spreading shrub growing to a height of about 3 metres by 3-4 metres wide. The leaves are very deeply lobed, occasionally with secondary lobes. The individual lobes are pungent, and 15mm by 4-5mm wide. The upper leaf surface is smooth and shiny whilst the underside is covered with dense silvery hairs. The leaf edges are rolled under. The new foliage has purple to bronze tonings. The flowers are of the toothbrush type and are borne terminally in the upper leaf axils. The perianth is about 10mm long and is covered with dense hairs. These hairs mask its deep purple colour. The reddish purple style is about 20mm long.
DIAGNOSIS: This cultivar differs from G. acanthifolia in that each lobe is usually entire compared with the usually sub-divided lobes of G. acanthifolia. The leaves are different from G. longifolia in that they are much more deeply lobed.
NOTE: Upon further continuing close examination of specimens growing at the Australian National Botanic Gardens it has been found that not all specimens have dense silvery hairs on the underside of the leaves. It appears that this characteristic can vary slightly between specimens in different situations. For this reason this characteristic should not have too great an emphasis placed upon it when determining this cultivar.
CULTIVATION NOTES: This cultivar is extremely vigorous and retains a very dense habit. The flowering period begins in late winter and continues through spring and sometimes into summer in Canberra.
