The flowers are hairy, cream-coloured, pale yellow or pink to red, the pistil 19–21.5 mm (0.75–0.85 in) long.

Flowering mainly occurs from July to March and the fruit is a glabrous follicle 18–23 mm (0.71–0.91 in) long.

[5] In 2006, the same authors raised the subspecies to species status as Grevillea polychroma in the journal Muelleria.

[6] Grevillea polychroma grows in forest at altitudes ranging from 80 to 940 m (260 to 3,080 ft) and is mainly found in areas around Buchan and Gelantipy in eastern Gippsland in Victoria.

The species is listed as "endangered" under the Victorian Government Flora and Fauna Guarantee Act 1988 and as "Rare in Victoria" on the Department of Sustainability and Environment's Advisory List of Rare or Threatened Plants in Victoria.
