Leucochrysum graminifolium, commonly known as pagoda rock daisy,^[2] is a flowering plant in the family Asteraceae. It is a small perennial with narrow leaves, yellow flower-heads and is endemic to New South Wales.

Leucochrysum graminifolium is upright, small, tufted perennial herb to 20 cm (7.9 in) high with a woody rootstock. The leaves are greyish-green, thread-like, crowded, up to 7 cm (2.8 in) long, edges rolled, upper surface smooth, lower surface woolly. The single daisy-like yellow flowers are on slender peducles about 8 cm (3.1 in) long, the bracts are spreading, 2–3 cm (0.79–1.18 in) in diameter, arranged in multiple rows. The outer bracts are light brown, the inner bracts pale yellow and the edges of the bracts are woolly at the base. Flowering occurs from October to March and the fruit is 2–3 mm (0.079–0.118 in) long and bristly.^[2]^[3]^[4]
