Sow indoors in early Spring or by wintersowing in containers outdoors. Lovely intense blue flowers that flower in the 1st year and that will also perform well in the garden. They produce tubers like Dahlias & should be lifted each year in the Fall, if gardening in colder climates. Wonderful in containers, rock gardens and the border.
