Panicle Hydrangea
Lewis Mock Orange

Panicle Hydrangea is a large, broad-leaf, deciduous shrub that is prized for its ornamental appeal. It is easy to care for, long-lived, and cold-hardy.

Depending on the variety, its flowers change color throughout the blooming period. Make sure you water Panicle Hydrangeas regularly to achieve the most notable color change.

Lewis Mock Orange is a flowering ornamental shrub that produces an abundance of white, fragrant blooms. The flowers have a sweet scent similar to orange blossoms, with a hint of pineapple. They bloom for several weeks from late spring to early summer, attracting pollinators and other beneficial insects.

Native to North America, Lewis Mock Orange is found from the southernmost portions of Alberta and British Columbia, and south into the northwestern United States. It makes an attractive shrub and can be used in hedgerows, pollinator gardens, and naturalization projects. Blooms occur on the previous year’s wood, so it is recommended to prune after it has finished flowering.
