Actinotus helianthi Labill. |

Actinotus helianthi, known as the flannel flower, is a common species of flowering plant native to the bushland around Sydney.
Despite its appearance, it is not a member of the daisy family but rather a species of the Apiaceae (formerly Mackinlayaceae) family, the same family as the carrot. Its generic name, meaning "furnished with rays", is derived from the Greek stem aktin-/ακτιν- "ray" or "spoke of a wheel" or "sunbeam", while its specific epithet is derived from its resemblance to the genus Helianthus. An iconic Sydney plant, its floral display has horticultural appeal which has seen limited use in the home garden and cut flower industry. It grows alongside the related lesser flannel flower (A. minor).
The flannel flower is generally a herbaceous shrub growing up to 50 cm (18 in) high, although rare specimens can be found to be 1.5 m (5 feet) high. The stem, branches and leaves of the plant are a pale grey in colour, covered in downy hair (rather like flannel in texture). The attractively lobed leaves are up to 10 cm (4 in) long and 7 cm (3 in) wide, with daisy-shaped flowerheads around 5 or occasionally 8 cm (2–3 in) in diameter. The bracts are cream to white in colour. Flowering occurs in spring and may be profuse after bushfires.
Flannel flowers grow in sandstone heathland in coastal New South Wales and Queensland, and are commonly seen around the Sydney basin in spring.
Plants may be propagated by seed or cutting and grow in a well-drained sunny position, and are suitable for use in a rockery or cottage garden. The Mount Annan Botanic Garden has been involved in selecting and breeding cultivars for the home garden and the cut flower industry. One selection was named Actinotus 'Federation Star', and was chosen to be the New South Wales floral emblem for the Centenary of Federation (1901–2001).
