Prunus nigra, commonly known as the Canada Plum, is a hardy ornamental and fruiting tree valued for its early spring blossom, attractive form, and wildlife-friendly nature. Native to North America, it is particularly well suited to cool climates and exposed sites, making it an excellent choice for UK gardens looking for a robust yet decorative tree.

In early spring, often before many other trees have woken up, Prunus nigra produces a profusion of white to soft pink blossoms on bare branches. These nectar-rich flowers are highly attractive to pollinators and create a light, elegant display that signals the start of the growing season.

As the year progresses, mid-green foliage develops, forming a rounded, spreading canopy. If conditions are favourable, the tree may produce small, dark purple-red plums later in the season, which are popular with birds and can also be used for jams and preserves. In autumn, the leaves turn yellow to warm amber tones, adding another layer of seasonal interest.

Prunus nigra is a versatile tree that works equally well as a specimen, within mixed borders, or as part of a wildlife-friendly or naturalistic planting scheme.
