Bur Cucumber

About Bur Cucumber

Bur Cucumber, or One-seeded Bur Cucumber, is a vigorous and fast-growing annual vine that provides excellent quick cover and a unique aesthetic to the naturalized garden. This native climber can reach lengths of 15 to 25 feet in a single season, using its branched tendrils to scramble over fences, trellises, or other vegetation. In late summer (August to September), it produces clusters of small, star-shaped greenish-white flowers that are highly attractive to honeybees, wasps, and flies. These are followed by distinctive, bristly seed pods containing a single seed. Native to much of Eastern North America, Bur Cucumber is typically found in moist, disturbed areas, floodplains, and along stream banks. It thrives in full sun to partial shade and prefers moist, rich soil. While it can be aggressive in small spaces, it is an invaluable plant for restoration projects and large-scale wildlife gardens where it provides dense cover for birds and small mammals.
