Black bindweed is an annual climbing vine that can reach up to 10 feet in height, twining around supports or sprawling along the ground. It produces small white or pinkish flowers from summer through fall and has heart-shaped leaves. This aggressive grower can quickly cover fences, trellises, or other plants.

In an HOA neighborhood

Black Bindweed takes more care to keep looking intentional in a front yard. Maintenance level: high. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.
