As an ornamental plant found mainly the numerous hybrid varieties usually uncertain origin use, but also some species (eg Bornholmmargerite ( Osteospermum ecklonis ), Osteospermum jucundum and Osteospermum fruticosum. The plants are intensively breeding and place in central Europe as a balcony and bedding plant increased encouragement, between 1997 and 2003 one could observe a tenfold increase in sales. because they do not stick veritable winter conditions in Central Europe ( below -5 ° C), they are hardy only conditionally. the ray florets are fruticosum in some varieties such as Osteospermum 'Pink whirls ' along tied together and remain open only at the top.
