Characteristics

Note: Originally Grevillea 'Austraflora MK.2' 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.
