About Olearia pannosa Hook.
Olearia pannosa Hook. is a spreading undershrub or shrub that typically grows up to 1 metre (3 feet 3 inches) tall and forms root suckers. Its branchlets are covered with woolly, Y-shaped hairs. The leaves are arranged alternately, and are egg-shaped or heart-shaped. They measure 30โ120 mm (1.2โ4.7 in) long and 18โ65 mm (0.71โ2.56 in) wide, borne on a petiole up to 22 mm (0.87 in) long. The upper leaf surface becomes glabrous as it matures, while the lower surface is covered with hairs that match those found on the branchlets. The daisy-like flower heads are arranged singly at the ends of branches, and measure 35โ75 mm (1.4โ3.0 in) wide on a peduncle 5โ25 mm (0.20โ0.98 in) long. The involucre is hemispherical and covered in woolly hairs. Each flower head holds 8 to 24 white ray florets and 18 to 50 yellow disc florets. Flowering takes place from September to November. The achenes produced are 5โ8 mm (0.20โ0.31 in) long, and the pappus is 8โ10 mm (0.31โ0.39 in) long. Both subspecies of Olearia pannosa are found in the south-east of South Australia. Only subspecies cardiophylla occurs in Victoria, where it grows in dry forest on rocky sites in scattered locations.
