Round Leaf Hawthorn
Limelight Hydrangea

Getting its name from rounded, toothed leaves, the Round Leaf Hawthorn is a winter hardy shrub that grows small, red, berry-like fruits.

Commonly used for landscaping, this shrub can also be found along stream banks and in wooded areas. Caution is advised when handling the Round Leaf Hawthorn, as it can have sharp thorns approximately 1" long.

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.
