Cultivar Name

Grevillea 'Poorinda Jennifer Joy'

Origin

Grevillea 'Poorinda Jennifer Joy' is said to be a hybrid between Grevilla speciosa and Grevillea linearifolia. Cultivar first received by the Authority on 10 September 1964. The applicant is Mr L Hodge of Bairnsdale 3875, Victoria.

Characteristics

This cultivar is a bushy shrub which grows to a height of 1.5m by up to 1m wide. The lanceolate leaves are ca. 25mm long by 5mm wide. The upper surface of the leaf is shiny and dark green and the underside is greyish due to a dense covering of short silky hairs. The leaves are flat with thick margins and have a pungent tip. Flowers are produced in terminal clusters on short lateral branches. The perianths are mauve and are ca. 10mm long. The style is up to 15mm long and much the same colour as the perianth. As the follicles develop the styles remain attached, during which time they colour to a rich red. Diagnosis: Grevillea 'Poorinda Jennifer Joy' leaves are intermediate between those of the parents. G. speciosa has ovate to elliptical leaves; G. linearifolia has linear leaves. However, at a glance the leaves of the cultivar more closely resemble those of G. speciosa. The flowers are very numerous in each cluster of G. speciosa and are most often deep red in colour. The flowers of the cultivar are much smaller than those of G. speciosa. The flower clusters of G. 'Poorinda Jennifer Joy' are larger than G. linearifolia, and individual flowers are slightly larger. The flower colour of this species is from white to pale pink. The cultivar has flowers intermediate in size and colour. Comparators: Grevillea linearifolia CBG 057292, 066609, 7907856. Grevillea speciosa CBG 035417, 005000.
