Neon Flash Spiraea
Lewis Mock Orange

Neon Flash Spiraea is a colorful, low maintenance, and multi-purpose shrub.

Late spring to fall you'll be drawn to its vibrant neon red blooms that rest on a neat mound of green foliage. If deer and rabbit are an issue on your property, consider planting Neon Flash Spiraea for its deer/rabbit resistance. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.

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.
