Dutchmans pipe

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.

The Dutchman’s Pipe is a fast growing, deciduous, woody, climbing vine. Featuring large heart-shaped leaves that overlap and often hide the flowers. The Dutchman’s Pipe namesake comes from the long yellow-green, brown or purple flowers that flare at the end, resembling Dutch smoking pipes.

The Dutchman’s Pipe will make a great screen or shade in your urban landscape, but does require support from a trellis or a fence. To control the growth, cut back in late winter.
