Black Cherry

Black Cherry is a common, weedy, early-successional tree.
The bark is smooth when young, with horizontally elongated lenticels.
Black Cherry produces masses of white flowers in spring. The specific epithet serotina means "late" - it flowers later that other native cherries.
The black cherry is a species in the subgenus Padus and is a deciduous tree growing to 15–30 metres (49–98 ft) tall with a trunk diameter of up to 70–120 centimetres (28–47 in), occasionally more, with flowers in racemes. The leaves are simple, 6–14 centimetres (2.4–5.5 in) long, with a serrated margin. The flowers are small (10–15 millimetres (0.39–0.59 in) diameter), with five white petals and about 20 stamens, and are fragrant; there are around 40 flowers on each raceme.
The fruit is a drupe, 1 centimetre (0.39 in) in diameter, green to red at first, ripening to black; it is usually astringent and bitter when eaten fresh, but also somewhat sweet
