Manchurian Lilac (Korean Lilac)

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.

Manchurian Lilac (aka Korean Lilac) is a medium-sized shrub that features fragrant clusters of pale purple flowers in late spring.

Manchurian Lilac is less affected by disease than other lilacs and will create a beautiful border, hedge, or privacy screen. If you are looking for a lilac for your shelterbelt, consider Common Purple Lilac or Villosa Lilac first.
