Helichrysum cymosum subsp. cymosum is a very attractive and easy-to-grow groundcover with small silvery grey leaves, covered with masses of bright yellow flowers in summer.

Helichrysum cymosum subsp. cymosum is a fast growing, well branched, spreading groundcover that can grow up to 1 m tall, but in the garden it is usually about 500 mm tall with equal spread. It has thin greyish-white woolly branches densely covered with leaves. The leaves are variable, mostly 8-15 (-42) x 2-4 (-15) mm, becoming smaller and more distant upwards. The upper surface of the leaf is covered in thin silvery grey, paper-like hairs (indumentum) that will strip like a skin when rubbed.

It flowers during summer, between September and April, but mainly in late summer and autumn, with bright canary-yellow flowers in flat-topped flowerheads that look like masses of small discs. Each flowerhead is a cluster of 6-20 flowers. The flowers generally have smooth tips, and a pappus of many bristles (a pappus is a whorl or tuft of bristles in place of a calyx).

There are two recognized subspecies of Helichrysum cymosum : subsp. cymosum and subsp. calvum which occurs mostly in the Grassland Biome. It ranges along the Drakensberg from the Eastern Cape region, along the KwaZulu-Natal and Lesotho border to the low Berg in Mpumalanga. The two subspecies can be confused but the difference between them is that subsp. calvum has smaller flowerheads with fewer flowers per flowerhead (4-7 flowers), generally narrower leaves, and it lacks a pappus.
