Kiowa produces larger fruit and has a longer harvest period than previously released Arkansas cultivars. Kiowa has thorned canes with large thorny leaves. Canes are self-supporting and require no trellis.
A major feature of blackberry Kiowa is its large fruit size. Kiowa produces large fruit during all the harvest season. The harvest season of Kiowa is long, with fruit ripening over six weeks compared to the four to six weeks harvest periods for most blackberry cultivars. Kiowa fruit are blocky, oblong and have an attractive, glossy black finish. Kiowa plants are not very vigorous. Fruiting row establishment has been good, using either plants or root cuttings. For best production, primocanes of Kiowa blackberry should be tipped in summer when they reach 1.0 to 1.2 m high, and lateral branches must be pruned to 40 cm during winter dormancy.
Kiowa variety is moderately resistant to anthracnose and there have been no disease problems following a fungicide program consisting of a single application of liquid lime sulfur at budbreak. There has been no orange rust on Kiowa. The reaction of plants to rosette has not been determined.
Plants have shown no visible injury following field exposure to minus 23 C, and annual ratings for cold hardiness indicate that Kiowa is enough hardy. The outstanding characteristics of Kiowa blackberry are its large fruit size, which is maintained throughout the harvest season, and its long ripening period.
Kiowa was very good blackberry for markets, in which large fruit and an extended harvest season are desired. Its fruiting characteristics also make Kiowa popular as a home-garden cultivar.
