Regenerates from seed or rhizomes. Presumed insect-pollinated.
Shrub 0.3–1 m tall. Branchlets angular and ridged, subsericeous between ridges, often secund. Leaves sublinear to narrowly oblong-elliptic or -obovate, often slightly incurved, 1–3 (–5) cm long, 1–3 mm wide; upper surface with midvein and intramarginal veins usually prominent and faintly granulose; margins shortly refracted; lower surface usually partly exposed, subsericeous. Conflorescence usually terminal, erect, level with or scarcely exceeded by leaf apices, usually pedunculate (peduncles to 15 mm long), regular, umbelloid, 6–16-flowered. Flowers adaxially oriented. Flower colour: perianth white to pink with brownish limb (hairs); style white to pink. Perianth subsericeous to tomentose outside, scantily bearded (rarely a few hairs only) inside opposite ovary. Pistil 7–8.5 mm long; style sharply geniculate 1–2 mm below apex, with minute hairs or papillae within apical 1 mm; pollen-presenter oblique. Follicle narrowly ovoid, 9–10 mm long, faintly warty. Fig. 23E–F.

Grevillea gariwerdensis is narrowly distinct from G. micrantha , which has the upper leaf surface often densely granulose, and lacks a beard on the inner surface of the perianth or at most has a few hairs surmounting a cushion-like pulvinus opposite the ovary. Grevillea gariwerdensis usually has a more conspicuous (albeit still scanty and short-haired) beard; it also has coarser, broader leaves, and a tendency to pedunculate or pseudo-pedunculate conflorescences (sometimes some sessile). Grevillea gariwerdensis is very similar indeed to G. parviflora , a N.S.W. endemic, which has a profuse beard of longer hairs on the inner surface of the perianth.
