‘Osage’ is the thirteenth release in a series of erect-growing, high-quality, productive floricane-fruiting blackberry (Rubus L. subgenus Rubus Watson) cultivars developed by the University of Arkansas Division of Agriculture. An enhanced effort in the improvement of flavor in blackberries has been underway in the Arkansas program for a number of years, and ‘Osage’ was developed with the intention of advancing flavor to a higher level in a thornless blackberry cultivar. ‘Osage’ ripens midearly, slightly before ‘Ouachita’ (Clark and Moore, 2005) and just after ‘Natchez’ (Clark and Moore, 2008). ‘Osage’ produces medium-sized berries, smaller than that of ‘Natchez’ but comparable to that of ‘Ouachita’. ‘Osage’ has excellent postharvest quality for the shipping market in addition to local market use. It is expected that ‘Osage’ will complement ‘Ouachita’ in the midearly to midseason harvest period.
