Shawnee blackberry variety

Plants of the Shawnee are highly vigorous and prolific and row establishment following planting is rapid. Both primocanes and floricanes are very erect and the fruit is readily accessible to both machine and hand harvest. Thorn size and density are medium. Canes are not thick, about 15 mm at the base. Leaves are large, have yellow-green color.
Date of first blossom is third week of April. Flowers have white-yellow color with slight pink at border.
Average ripening date is third week of June. The harvest period is longer than most other erect varieties, it produces well for a full month. This long fruiting period results in high total yields and the Shawnee has outyielded the many other varieties. Fruit clusters are medium-large, cymose, and are borne on the periphery of the plant canopy, providing easy access to harvest. Flower fertility is high and clusters are well filled. The fruit are conic or rounded in shape, bright black in color and large in size (avg. 7 g). Fruit size is maintained well throughout the season, without the significant decline in size of secondary and tertiary fruits common in other varieties. The fruit are firm at maturity. Shape is medium long conic or rounded. Seeds are large. Flavor is midly acid.
