Rudbeckia laciniata, the cutleaf coneflower,[1] is a species of flowering plant in the family Asteraceae.

[2] Its natural habitat is wet sites in flood plains, along stream banks, and in moist forests.

8 to 15 irregularly arranged, foliage-like, smooth to hairy bracts have a length of up to 2 cm and usually a ciliate border.

[3][7] The six varieties are:[8] Rudbeckia laciniata is widely cultivated in gardens and for cut flowers.

Numerous cultivars have been developed, of which 'Herbstsonne' ("Autumn sun") and 'Starcadia Razzle Dazzle'[9] have gained the Royal Horticultural Society's Award of Garden Merit.

[12] Rudbeckia laciniata has long been cultivated as an ornamental plant and came to Paris in the private garden of Vespasias Robin at the beginning of the 17th century.

Caspar Bauhin also received this ornamental plant from Robin in 1622, who described it as 'Doronicum americanum laciniato folio'.

Anton Johann Krocker reported about it in 1787 in Queistal near Flinsburg in eastern Upper Lusatia.

As an ornamental plant, varieties are used in parks and gardens in temperate areas, for example also filled forms.

[6][13] The Lady Bird Johnson Wildflower Center[14] notes that "Because it spreads rampantly by underground stems, cut-leaf coneflower is only appropriate for large sites."
