A free-flowering and popular Californian annual with grey-green finely divided leaves and bright orange-yellow flowers. There are now many charming and much-improved varieties, such as Carter's Carmine King, with beautiful carmine-rose-coloured flowers; Mandarin, orange crimson; Rose Cardinal, delicate bright rose; Golden West, almost entirely orange; and others. The ordinary form is little better than a weed, but the other varieties make charming border flowers, and are easily raised from seeds sown about the middle of March and thinned out about 1 ft. apart.
