Grevillea 'Bonnie Prince Charlie'

NOTE: Originally Grevillea 'Austraflora MK.2'

ORIGIN: Grevillea 'Bonnie Prince Charlie' is a hybrid between G. rosmarinifolia and G. alpina (a form from the Grampians). It arose in cultivation at Austraflora Nursery, Montrose, Victoria. It is named for Prince Charles, the Prince of Wales. The cultivar was first received by the Authority in September 1982. Registration applied for by Molyneux Nurseries Pty Ltd of Montrose, Victoria.

DESCRIPTION: This cultivar is a moderately dense shrub to 60cms tall by ca. 1m wide. The branches are reasonably erect off the main stem but arch further down their length. The leaves are lanceolate and are between 2 and 3cm long by 1 to 3mm wide and darker on the upper surface. The margins are rolled under. The leaves terminate with a short, recurved mucronate tip and are covered with sparse silky hairs both above and below. The new foliage and branchlets are densely covered with brownish hairs. The flowers are found in terminal racemes on the branchlets. They are orange red at the base of the perianth and dark red along the spine becoming bright yellow-green on the perianth limb. The perianth is almost glabrous with some scattered silky hairs. The style is ca 2cm long, densely covered with silky hairs on the ovary and occasional hairs along the style. The flowering season is from August to September and late summer to autumn in Melbourne.

CULTIVATION NOTES: This cultivar was selected in the late 1970's. The drought hardiness has not been tested though the applicant considers it would be tolerant. It is frost hardy. Grevillea 'Bonnie Prince Charlie’ will grow in dry to moist well-drained positions in full sun to semi-shade. It is a useful container plant and has bird-attract qualities. The cultivar must be grown by vegetative means to ensure retention of its desirable characteristics.
