Annabelle Hydrangea
Lewis Mock Orange

Annabelle Hydrangea is a cold hardy shrub that is well known for its large, compact clusters of white flowers. Unlike other flowering species, Hydrangeas do best in partial shade. However, they are capable of growing in full sun if the soil is kept consistently moist.

Blooms occur on new wood, so regular pruning is encouraged in late winter. Try Annabelle Hydrangea as a border or on its own.

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.
