Rainy Side Notes

 

Discovered in 1818,Clematis montana was later introduced into cultivation by Lady Amherst in 1831. The vigorous vine is a popular clematis choice, not only for its rampant growth but also for its wonderfully fragrant flowers. When the clematis is in full bloom, its vanilla-like scent wafts through the garden like a Pied Piper beckoning all to follow the intoxicating fragrance. Following the drifting fragrance, we find the gift waits, a large flowing vine, cascading down like a gentle waterfall, dripping with captivating white flowers.

Small trees and flimsy arbors are not suitable for a vine as large as C. montana. It needs a substantial structure to climb, like a large shed, pergola or a long stout fence, which is more to the vine's requirements. If growing on your property line, be mindful of your neighbor's shrubs and trees, as this opportunist vine will be covering anything it can reach. Your neighbors may not appreciate your rambunctious vine smothering their precious plants.
