Japanese Mock Orange Seeds

Japanese Mock Orange is a handsome evergreen shrub prized for its dense glossy foliage, highly fragrant spring flowers, and exceptional versatility as a hedge plant. Native to Japan, Korea, and parts of eastern Asia, it has become one of the most widely planted evergreen hedges in warm temperate and coastal regions around the world.

Its naturally dense branching habit forms an attractive screen that can be maintained as a formal clipped hedge or allowed to develop into a graceful informal barrier. During spring, clusters of creamy white flowers release a sweet citrus-like fragrance often compared to orange blossoms, giving rise to its common name.

For gardeners seeking beauty, privacy, fragrance, and year-round greenery, few hedge plants offer as complete a package as Japanese Mock Orange.
