The rock daisy, as Heterolepis aliena is commonly known, grows from the Cape Peninsula to the Gariep River and eastwards into the Karoo to Laingsburg. The plant in the photo, seen flowering among rocks in Bainskloof during October, has fairly grey leaf colouring, although the plant is not as cobwebby as seen on those growing in the Peninsula and around Caledon. A rocky crevice is a common perch for this species, otherwise sandstone slopes.
The needle-like leaves of H. aliena vary in length between 1,5 cm and 3 cm. They are crowded at the tips of the many branched stems, curving inwards slightly. The margins are rolled under and sparsely toothed. The lower leaf surface, what little can be seen of it, is white with woolliness (Manning, 2007; iSpot).
