The Dutchman’s Pipe is a vigorous deciduous climbing vine valued for its large heart-shaped leaves and unusual curved flowers that resemble old-fashioned smoking pipes. The dense foliage creates a lush, tropical appearance and is excellent for quickly covering arbors, pergolas, fences, or privacy screens. In late spring to early summer, the unique greenish-purple flowers appear tucked beneath the foliage, adding botanical interest. In the Regina area, Dutchman’s Pipe benefits from a protected location, as prairie winters can cause stem dieback, though established roots may recover in favorable microclimates.
