Regenerates from seed and rhizomes.

Erect and open to low and dense shrub, 0.4–1.8 m tall. Leaves entire, oblong-elliptic to broadly elliptic or -linear, usually 20–45 (–60) mm long, 4–18 mm wide; margins recurved to loosely revolute; upper surface granulose; lower surface tomentose. Inflorescences terminal or axillary, usually simple, usually decurved, a short subsecund 2–8-flowered cluster, acropetal; floral rachis 1–5 mm long, pubescent. Flowers adaxially acroscopic. Flower colour: perianth usually red in basal half, shading to yellow above, or sometimes red and white, apricot and white, or rarely all yellow; style green at base, shading to pink or cherry red above with a green tip, rarely light green throughout. Perianth basally dilated, pubescent to tomentose outside, bearded inside in lower third. Pistil 18–25 mm long; ovary sessile, villous; style dorsally villous in lower half, glabrescent above, scarcely exserted in late bud; pollen-presenter lateral. Follicle ellipsoidal, 14–16 mm long, tomentose, longitudinally ridged. 

Occurs in south-eastern Vic., where known only from the Colquhoun State Forest E of Bruthen. Grows on red siliceous or pale granitic sands in shrubby patches in dry sclerophyll forest. Flowers July–Feb. Map 260.

Grevillea celata has a prominent, ascending linguiform or shovel-like thin-edged nectary extending clearly above the toral rim. It is generally similar to the closely related species G. chrysophaea (which is not rhizomatous and lacks red colouration on the perianth), and G. alpina (which is not usually rhizomatous, has a more prominent and spreading tongue-like nectary, and usually a shorter pistil). Grevillea celata is only narrowly distinct from, and shares features of, these two relatives and is unstable in several character states (e.g. flower colour, perianth width); it may be of recent hybrid origin.
