The flowers are rich green and yellow to orange with a deep maroon to purplish black style covered with white hairs, the pistil 30–36 mm (1.2–1.4 in) long.

Flowers occur throughout the year with a peak from June to September and the fruit is a greenish, elliptic, shaggy-hairy follicle 16–19 mm (0.63–0.75 in) long.

[5][6][7][8] Grevillea venusta was first formally described in 1811 by Robert Brown in Transactions of the Linnean Society of London, after he collected the type specimen near Cape Townshend (near Shoalwater Bay) in eastern Queensland in August 1802.

[11] Byfield spider flower is restricted to central eastern Queensland where it grows in forest and woodland in rocky places and along creeks between the Many Peaks Range and Shoalwater Bay.

[2][8] This species has been cultivated since the early 1970s and is suitable for use in small gardens, where it grows readily in a sunny position with good drainage.
