Chesapeake blackberry, which has a Shawnee cultivar as parent, may be distinguished from othe large-fruited thorny varieties, such as Kiowa, by the recurvature of its spines and flavor of its fruit. It may be distinguished from Black Butte by the type of spines and its erectness, compared to the semi-erect habit of the large fruited Black Butte. The presence of thorns and the size of the fruit distinguish Chesapeake from popular thornles cultivars such as Arapaho, Navaho, Hull Thornless, Triple Crown and Chester Thornless. Chesapeake blackberry cultivar was bred by University of Maryland.
Plants are very erect, growing to 4 m or taller when mature. Chesapeake produces a moderate number of root and crown-stems. During the growing season, primocanes are light green colored with a light red blush in full sun, fluted or moderately grooved, usually branched, very erect with arching branches and very vigorous. Floricane color is brown. Canes can flower from all live buds in April to May depending on region, and fruit from mid June to late July.
Cheasapeake produces fruit which is much larger and more flavorful than the Black Butte and Kiowa. Fruit is decidedly thick elongate (commonly up to 4 cm in length and 2 cm in width), very large (15-22 g primary fruit) and somewhat asymmetrical due to variation in drupelet placement. The fruit is very juicy when crushed and the drupelets are relatively large. Seed size is large, averaging 4.6 mg per seed fresh weight. Fruit flavor is sweet, even when the fruit is unripe.
The plant is field resistant to many of the common pests and diseases, for example mildew and Phytophthora fragarae, root rot and fruit rot.
Cheasapeake is moderately cold hardy, it is not recommended for areas where the minimum winter temperature is less than minus 18 С.
