Grevillea maxwellii is known from a few, small populations on private land near Pallinup in Western Australia. It is a small shrub 0.5 to 1 metre in height by about 1 metre in width with overlapping branches giving a layered growth habit. Leaves are up to 75 mm long with 3 to 6 narrow, linear-shaped lobes terminating in a pungent point. The deep red flowers occur in pendent clusters at the ends of the branches or in the leaf axils in winter and spring.
Because of its rarity, G.maxwellii is in limited cultivation but indications are that it is adaptable to cultivation even in areas of high summer humidity where plants from the south west often struggle. However, plants are likely to be most successful in areas with a dry summer climate. It is an attractive, densely foliage plant which should become popular in native gardens due to its modest size and attractive flowers. Moist, well drained conditions, preferably in a sunny position, are likely to be preferred in cultivation. Like most grevilleas, the flowers attract honey-eating birds
Cuttings of hardened, current season’s growth strike readily. Limited experience indicates that the species can be grafted onto Grevillea robusta and G. ‘Poorinda Royal Mantle’. If the compatibility of these grafts proves successful in the long term, grafting will provide a means of extending the range of successful cultivation.
