Plant details

This once fashionable South American species is sometimes known as the four o'clock flower because its red, yellow, white and lilac blooms only open in late afternoon and will then spread their perfume over a large area in the still evening air. This is not a hardy plant, and should be planted like dahlias after the last spring frosts. It likes very fertile soil, in which it will form a large handsome bush that flowers prolifically until mid-autumn, when the tubers can be lifted and dried for storing. Plants are usually raised from seed in a blend of bright colours.
