Grevillea ‘Splendour’ is a hardy, colourful hybrid whose parentage is a trifle confused. One parent is reputed to be G. shiressii whilst the other may be G. oleoides or a G. victoriae hybrid. Regardless of this confusion Grevillea ‘Splendour’ is well worth cultivating.
The hybrid arose as a chance seedling in a Melbourne Garden in 1976. The cultivar was first registered November 1988.
Grevillea ‘Splendour’, in our cold climate garden, reaches a height of two metres with a spread of one metre. The narrow, lance-like leaves are blue-green and six centimetres long.
The appearance of the leaves is reminiscent of G. shiressii, one of the parents. Large clusters of bright red flowers are carried for most of the year. Honeyeaters are fond of the blooms. Both foliage and flowers are attractive features.
Grevillea ‘Ruby Clusters’ appears to be an alternative name.
We have a number of specimens in our garden and they have proved to be drought resistant, frost tolerant and free flowering.
To maintain dense growth regular pruning is appreciated.
