Cup-and-Saucer Vine: A Field Guide
A fast-growing flowering vine with cup-shaped purple (or sometimes white) flower, cup-and-saucer vine will quickly camouflage a fence or trellis and also can be trained as a hedge.
Cobaea scandens hails from warm climated (it’s at home in Mexico and Venezuela) and should be grown as an annual in regions colder than USDA growing zone 9.
With its speedy growth rate and cloaking tendencies, cup-and-saucer brings to mind another purple climber, morning glory, but C. scandens has longer-lasting flowers and stems that with beautiful draping effect, making it a favorite for floral arrangements as well.
Before planting, make sure cup-and-saucer is not considered an invasive weed in your region. Another alternative climber to consider is Passionflower. And if it’s an elegant perennial vine you’re looking for, well-behaved Clematis will tolerate colder winters.
