Grevillea 'Mason's Hybrid'

ORIGIN: Grevillea 'Mason's Hybrid' arose as a seedling from seed collected from an upright glaucous form of Grevillea bipinnatifida. The seed was grown at the Kentlyn Nursery, Georges River Road, Kentlyn, New South Wales. As the seedlings grew a number showed certain differences and were selected out and grown on. As the plants grew it became more obvious that they were hybrid seedlings. Because of certain characteristics the other parent was presumed to be G. banksii. Cultivar first received by the Authority on 2 August 1980. Applicant: Mr J B Mason, SW Native Flora, Old Mill Road, Northcliffe, 6262.

DESCRIPTION: This cultivar grows into a bushy shrub plus/minus 1.5m tall by up to 2m across. The foliage is very similar to another G. banksii x G. bipinnatifa hybrid, G. 'Robyn Gordon'. The racemes of flowers are 12cm long by 10cm in diameter. For the individual flowers the perianth parts are plus/minus 18mm long and the style plus/minus 25mm. Flowers can be found at all times of they year. The flowers are apricot coloured ant the styles are red.

DIAGNOSIS: The foliage of G. 'Mason's Hybrid' can be difficult to distinguish from the foliage of G. 'Robyn Gordon'. The flowers may be easily distinguished. G. 'Mason's Hybrid' has apricot coloured flowers whereas G. 'Robyn Gordon' has red flowers. The flower racemes are more open and spreading than in G. bipinnatifida and are not held erect as in G. banksii. The distinguishing features from another hybrid with the same parentage, G. 'Superb', are that G. 'Mason's Hybrid' grows taller, and flower colour is different. The flower is also a little smaller than G. 'Superb'. The style tips are quite different colours.

CULTIVATION NOTES: G. 'Mason's Hybrid' is drought hardy. The new growth is cut back by frost but is otherwise hardy. This cultivar must be propagated by vegetative means to preserve the cultivar form.
