An introduction from New York Experiment Station. Darrow has proven to be the most reliable producer of large crops of top quality fruit. Berries measure 1" long and 3/4" wide, are attractive, firm, juicy, and have honey sweet, true blackberry flavor. Excellent for all purposes. Plants are hardy, rust resistant, and produce well at an early age. Canes are sturdy and upright growing. Fruit ripens in July and continues for 2-3 weeks. (Zone 5-8)
