Grevillea 'Boongala Spinebill'

ACRA 1612

Applicant: Neil Marriott, on behalf of the ANPSA Grevillea Study Group

Origin: A spontaneous seedling introduced to the market by the late Sid Cadwell from his nursery 'Boongala', which he operated in the 1960s near Annangrove, New South Wales. The cultivar was widely cultivated throughout the east coast of Australia between 1970 and 1990 but gradually disappeared from nursery outlets in the 1990s. It has been recently revived in a limited way with several wholesale nurseries carrying stock.

Characteristics: A spreading, dark green, bushy, infertile shrub 1.5–2.5 m high and 2–3 m wide with coppery red new growth. Conflorescence to 60 mm long flowers 80–100 mm across x about same long, bronze-red silky, can be produced most of year but late Spring to Summer; leaves 70–120mm long x about same, palmate with slender petiole, broadly 5-lobed green.

Cultural Notes: Highly ornamental small shrub. Suited to a range of acidic and alkaline sandy to clay loam soils that drain moderately well. Best in a sunny site but will tolerate some shade. Frost resistant to -6°C. Responds well to pruning.

Propagation: Cuttings of semi-firm growth. Rooting hormones in powder or liquid form of IBA will be beneficial.

Uses: General ornamental planting; container plants (if grown in a large container).

Labels: Norwood Industries Pty Ltd have produced a label for this cultivar.
