Empress Tree

Canada Plum is a cold-hardy wild plum native to North America with small red fruit. They ripen in mid to late summer, with bitter, astringent skin surrounding sweet, slightly acidic flesh that clings to the stone. While some enjoy eating the plums fresh, they are more commonly used for baking and preserves. It is considered a universal pollinizer for other plum varieties and is often used for grafting or as a rootstock.

White to pink flowers appear in spring, often before the leaves, providing an early source of nectar and pollen for native bees and other pollinators. Birds and other wildlife also feed on the fruit, adding to its ecological value. Canada Plum can grow as a small tree or large, multi-stemmed shrub. It is well suited to a variety of projects, including fruit orchards for cross-pollination, as well as pollinator plantings, naturalization, and restoration projects.

The Empress Tree is a fast growing, ornamental shade tree. It has purple, fragrant flowers that are quite attractive. The flowers emerge before the leaves in early spring. The leaves of this tree can grow very large, up to 30 cm long.

As one of the fastest growing trees in the world, this tree has been given considerable attention for carbon sequestration projects. It drops many seeds which can make it invasive in warmer climates. Please do some research and plant the right tree in the right place.

The Empress tree’s genus name comes from Princess Paulowna, daughter of Tsar Paul I of Russia.
