Arctotis is a genus of annual and perennial flowering plants in the family Asteraceae (order Asterales), commonly known as "African daisies" or, in Afrikaans, "gousblom" (meaning "gold flower"). The genus is native to the dry, stony slopes of southern Africa and comprises roughly 70 species of herbs and subshrubs.
Plants in the genus produce the characteristic daisy-like composite flower heads typical of the Asteraceae family, with ray florets surrounding a central disc. A distinctive trait is that the flowers tend to close in the late afternoon and in overcast or dull weather, a behaviour linked to pollinator activity. Foliage is often grey-green and somewhat woolly or tomentose, an adaptation to the arid, sunny conditions of their native habitat.
Some species were formerly or alternatively placed in the closely related genus Venidium, and the boundaries between these genera have been revised over time. Arctotis is closely allied with Arctotheca, another southern African daisy genus.
The genus has attracted considerable horticultural interest. Numerous cultivars and hybrid selections have been developed for garden use, offering flowers in a wide range of colours including white, yellow, orange, red, and pink. The hybrid grex A. × hybrida encompasses many popular garden forms; among them, 'Flame' has received the Royal Horticultural Society's Award of Garden Merit. In temperate regions outside southern Africa, tender perennial species are commonly grown as half-hardy annuals.
Etymology
The genus name Arctotis derives from the Greek words arktos (bear) and ous/otos (ear), thought to refer to the scales of the receptacle or the shape of the fruit. The common name "African daisy" reflects both the plant's origin in southern Africa and its resemblance to a classic daisy. The Afrikaans name "gousblom" means "gold flower."
Distribution
Arctotis is native to dry, stony slopes and open habitats across southern Africa, with the greatest diversity in the Cape Floristic Region of South Africa. Species occur in summer-dry, winter-rainfall areas typical of fynbos and Namaqualand, as well as in semi-arid scrubland further north into Namibia. Several species and hybrids are widely cultivated well beyond their native range.
Cultivation
Arctotis species and hybrids are popular ornamental plants grown for their showy, daisy-like flowers in colours ranging from white and yellow to orange, red, and pink. They thrive in full sun and well-drained soils, tolerating dry conditions once established — a reflection of their arid southern African origins. In frost-prone temperate climates, tender perennial species are typically treated as half-hardy annuals, started under glass and planted out after the last frost. Numerous cultivars have been selected for longer flower-opening times, since wild plants close their flowers in late afternoon or dull weather. The hybrid 'Flame' holds the RHS Award of Garden Merit, and vigorous garden forms such as 'Pink Sugar' and 'Large Marge' are widely available.
