Pin Cherry - Prunus pensylvanica
Pin Cherry trees produce small, edible fruits, that are sour when raw, but make excellent preserves. However, all non-fruit parts of the tree contain toxins and are inedible. Pin Cherry grows quickly, and can also spread through suckers, making it useful for stabilizing eroding soils and riverbanks. Pin Cherry like open woodlands, and will readily colonize recently disturbed stands, helping to begin the reforestation process. These small trees only live about 40 years, but they produce a lot of fruit once mature, which many animals rely on in late summer. Pin Cherry fruits are so popular with songbirds that this tree is commonly known as Bird Cherry!
