Taxonomy

Grevillea ripicola was first formally described in 1974 Alex George in the journal Nuytsia based on plant material he collected at Collie in 1965. The specific epithet (ripicola) means "growing on river banks".

Distribution and habitat

Collie grevillea grows near creeks in Jarrah forest, mainly between Collie, Donnybrook and Bridgetown in the Jarrah Forest bioregion of south-western Western Australia.

Conservation status

Grevillea ripicola is classified as "Priority Four" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is rare or near threatened.

Use in horticulture

This grevillea is well adapted to cultivation and is frost hardy and fast-growing. Its dense foliage provides habitat for small birds. It is adaptable to most soils and conditions and has been grown on the east coast, south from Sydney.
