Hairy Fire Aster is a small, tufted perennial daisy from the mountains of South Africa's Western Cape, growing up to about 40 cm tall with woolly leaves. It is a rare local endemic that flowers mainly after fire or soil disturbance, so it suits gardeners who can mimic those conditions in a sunny, well-drained spot.

About

Mairia hirsuta is a tufted perennial, herbaceous plant of up to 40 cm (1+1⁄3 ft) high, that is assigned to the family Asteraceae. Most of its narrow to broad elliptic or inverted egg-shaped leaves are part of the basal rosette, have margin that is rolled under, with rounded or pointy teeth or with some peg-like extensions, lightly woolly on the upper surface and densely woolly on the underside, but always the green remains visible. Flower heads have been found from July to November, mostly after a fire or when the soil has been disturbed. The species can be found in the southern mountains of the Western Cape province of South Africa.

Where it grows

Mairia hirsuta is a local endemic of the Langeberg between Swellendam, Suurbraak and the neighbouring Warmwaterberg. It is considered a rare species, because although it occupies a range of only about 59 km2 (23 sq mi), it is well protected in the Boosmansbos Wilderness Area and the Marloth Nature Reserve. Here it grows in a fynbos vegetation on the steep, south-facing slopes.
