Arctotis acaulis is a fast-growing perennial that is best grown as an annual, with large orange, yellow, salmon or cream daisies in spring and early summer.
Arctotis acaulis is a stemless perennial 200 - 300 mm tall, with a tuberous rootstock and a basal tuft of leaves, i.e. they arise directly from the rootstock. The leaves are roughly hairy above and grey-felted underneath, divided into broad lobes cleft almost to the midrib (pinnatifid), with a large rounded terminal lobe and smaller lateral lobes that diminish in size towards the base of the leaf (lyrate).
Large (70-100 mm in diameter), solitary, daisies with dark centres and bright yellow, orange, salmon pink or cream rays are borne in succession at the tips of ±300 mm long, thick, roughly hairy flower stalks in late winter to early summer (July to November), peaking during spring (August-October). The flower stalks also arise directly from the rootstock. The disc florets are black when closed, opening to reveal yellow stamens and stigma. There is often a black spot or band at the base of the ray florets, creating a black ring around the centre of the daisy. Some plants also have a bright yellow band.
The fruit is an achene (a small, dry, indehiscent, one-seeded fruit that does not split open), with a well-developed pappus of papery scales and basal tuft of hairs. In cultivation they hybridise quite freely with other species of Arctotis and a wider range of colours develops over a few generations, including pink, maroon and red. The banding colour also varies.
