Grevillea 'Jubilee'

Formerly: Grevillea 'Austraflora Jubilee'

ORIGIN: Grevillea ' Jubilee' is a presumed hybrid between G. rosmarinifolia and G.alpina. The cultivar arose at Austraflora Nurseries in Montrose. The cultivar was first received by the Authority on the 24th September 1982. The applicant is Austraflora Nurseries Pty Ltd, P.O. Box 146, Montrose 3765.

DESCRIPTION: Grevillea' Jubilee' is a shrub of medium density and which grows to a height of more or less 1m. It has erect, dark green foliage; the leaves are linear elliptical, more or less 25mm long and 30mm wide with pungent tips and slightly revolute margins. The flowers are in terminal clusters and are distinctively coloured. In bud, the perianth is mostly yellow-green but dark red on the dorsal side. At maturity it becomes more yellow on the limb and at the base and is a contrasting red brown on the dorsal side. The flowers open to release a thick red-brown style with a large tan coloured pollen presenter (style end).

DIAGNOSIS: This cultivar has the appearance of a compact form of G. rosmarinifolia but while the flowers are the approximate size and waxiness of that species, the colouring is decidedly different. Grevillea ' Jubilee' is less hairy and has bigger flowers than G. alpina as well as being a slightly larger shrub.

OTHER NOTES: This cultivar is frost hardy in Melbourne but its drought resistance has not been fully tested. It must be propagated by vegetative means to preserve the cultivar form.

COLOUR CODE: R.H.S. Colour Chart 1966. The colour coding given is that taken at anthesis.

Perianth: Mostly around yellow group 7B at the base and limb with red group 47A/B on the dorsal side.

Style: red group 46A.

Pollen presenter: greyed brown group 199A.

Foliage: green group 137B.
