Amelanchier

A small native tree with white spring flowers, edible summer berries, and copper to red fall color.

Snowy mespilus is a naturally occurring hybrid (Amelanchier arborea × A. laevis) that originated in eastern Canada and became one of Europe's most popular small ornamental trees after widespread cultivation from the 18th century onward. It earns its keep three times over: clouds of white star-shaped flowers in spring, sweet edible dark-purple berries in summer that birds strip within days, and reliable orange-red autumn colour. The honest catch is its behaviour outside the garden: in the Netherlands, Belgium, and parts of Germany it has escaped cultivation so thoroughly that it is classified as an invasive on heathlands and acidic dune grasslands, where it shades out specialist low-growing flora - a consequence worth knowing before planting near conservation land.
