Helichrysum cymosum

Helichrysum cymosum

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.

Common names: gold carpet (Eng.); goue tapyt (Afr.); impepho (isiXhosa)

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.

Distribution and habitat

It grows in big straggling clumps, often in moist areas such as the hollows between dunes, amongst shrubs in Cape scrub and on forest margins. It ranges from the Western Cape, including the Cape Peninsula, eastwards along the coastal mountain ranges of the Eastern Cape and as far as Lake St Lucia in KwaZulu-Natal.

Uses

Like in many other Helichrysum species, the leaves are aromatic. Traditionally, people of the Eastern Cape use dried leaves as a pain reliever, by inhaling the smoke of burning leaves. Fresh leaves are traditionally boiled in water and drunk as a tea for coughs and colds. Leaves are also traditionally used in wound dressings and to prevent infections.

Growing Helichrysum cymosum subsp. cymosum

This is an easy plant to grow and an excellent hardy ground cover for dry areas. It can also be used as an edging plant, in mixed borders, containers, window boxes, as well as herb gardens and scented gardens. It is a plant that tolerates salty air and grows well in sandy soils, which makes it a good plant for coastal gardens. It grows well in full sun and semishaded areas.

Helichrysum cymosum subsp. cymosum is easy to propagate from cuttings rooted in a sand-based growing medium with the addition of compost and fertilizer for nutrients. Seeds are sown in autumn or spring.
