Limelight Hydrangea
Canada Plum

Limelight Hydrangea is a flowering shrub that is known for its green flowers. As they mature, the flower colour changes from a pale green to a creamy white, followed by shades of pink and red. Hydrangea flowers persist longer compared to other flowering shrubs, blooming from late July into fall. They are a popular choice for flower arrangements.

The Limelight Hydrangea can be grown as a stand alone shrub, as a hedge, or incorporated into a flower garden. Blooms occur on new wood, so regular pruning is encouraged in late winter. This is an award winner from the Proven Winners® collection.

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.
