Larkspur has been a mainstay of American cutting gardens since colonial times. A hardy self-seeding annual, it makes an excellent fresh or dried cut flower. Larkspur plants prefer cool summers and require vernalization (a period of cool temperatures) for the first 6 weeks of growth in order to trigger flower development. See our larkspur production guide for more information. Our larkspur varieties are selected by our research team for superior performance as a cut flower. Choose from conventional and organic larkspur seeds, as well as a large range of colors.
