D.×grandiflorum (Ramat.) Kitam. (D. indicum × ?), was a name briefly used for the Florist's Chrysanthemum, which was probably raised in China and is an erect or spreading perennial herb or subshrub to 1.5 m tall with clusters of large capitula (to 30 cm across) and white, yellow or pink ray florets. It is now retained in Chrysanthemum ×morifolium Ramat. See under this name for a brief history.
