About Isopogon asper R.Br.
Isopogon asper R.Br. is a shrub that usually reaches a height of 0.2 to 0.8 meters (7.9 inches to 2 feet 7.5 inches). It has reddish-brown branchlets covered in hairs. Its leaves are crowded, growing up to roughly 20 millimeters (0.79 inches) long, and are pinnate with cylindrical or grooved leaflets attached to a petiole up to about 13 millimeters (0.51 inches) long.
The flowers of Isopogon asper are arranged in sessile, densely clustered, flattened-spherical heads that can be up to 40 millimeters (1.6 inches) in diameter. The involucral bracts are egg-shaped with pointed tips, and the individual flowers are around 18 millimeters (0.71 inches) long, pink, and glabrous. Flowering takes place from June to October. After flowering, the fruit develops as a hairy nut, with multiple nuts fused together into a spherical head up to 20 millimeters (0.79 inches) in diameter.
This species of isopogon grows in low open heath, most often in soil that formed from granite. Its range extends from Harvey to near Jurien Bay in the south-west of Western Australia.
