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.
