Olearia stilwelliae is a species of flowering plant in the family Asteraceae and is endemic to New South Wales, Australia. It is a shrub with scattered elliptic or egg-shaped leaves, and pale blue, white and yellow, daisy-like inflorescences.
Olearia stilwelliae is a shrub that typically grows to a height of up to 60 cm (24 in). Its leaves are elliptic or egg-shaped, 25–134 mm (0.98–5.28 in) long and 16–35 mm (0.63–1.38 in) wide on a petiole 5–20 mm (0.20–0.79 in) long, the edges of the leaves sometimes toothed. The upper surface of the leaves is glabrous and the lower surface covered with felt-like hairs. The heads or daisy-like "flowers" are arranged singly in leaf axils on a peduncle up to 330 mm (13 in) long, and are 40–48 mm (1.6–1.9 in) in diameter. There are 8 to 12 usually white or pale blue ray florets, surrounding about 35 yellow disc florets, the ligule 15–18 mm (0.59–0.71 in) long. Flowering occurs from June to October and the fruit is a silky-hairy achene, the pappus with 77 to 100 bristles.[2][3]
