Canes and floricanes are erect in growth habit. Plants are thornless.
Kelly is early-ripening variety (first half of June in warm areas), the average floricane fruiting period is about 60 days.
Fruit yields of the new cultivar on floricanes are on average 4 kg. The fruit is round in shape and glossy with a uniform black finish. Berries of Kelly cultivar are medium (~ 6g) in weight. Kelly exhibits excellent fruit fertility with full drupelet set. Fruit firmness is a noteworthy characteristic and is near crisp in texture, and is consistent whether in rainy or dry periods of fruit maturity. The flavor is sweet and sub-acid. The overall postharvest storage potential of fresh fruit of the Kelly blackberry cultivar is greater than that of Osage and Natchez. Fruit and flower clusters are medium-large, cymose, and are mostly borne on the periphery of the plant canopy, providing easy access to harvest.
Plants and fruit have shown slight susceptibility to anthracnose, have shown no evidence of susceptibility to orange rust. Also Kelly have shown susceptibility to cane and leaf rust.
Kelly is hardy to minus 8C. Temperatures lower than this have resulted in crop reduction.
