blossoms

The American bilberry is a 1 to 4 meter high, heavily branched subshrub with smooth or slightly hairy branches. The short-stalked, simple leaves are oblong-round to elliptical and 2.5 to 8 cm long, usually tapering to a point and bristly hairy on the edge, but at least finely hairy along the veins of the underside.

The grapes appear before the leaves and are as long as the inflorescence stems, the bracts are obsolete. The crown is 6 to 12 mm long, with five white or light pink, cylindrical or slightly tapered tips near the throat. The berries are round, dark blue fruits and reach a diameter of 6 to 8 mm.

The number of chromosomes is 2n = 48.
