Wild bean is a native climbing vine that produces small purple flowers in summer and fall. It can reach up to 20 feet in height when given proper support, making it useful for covering trellises, fences, or arbors. The plant dies back to the ground each winter and regrows from its roots in spring.
In an HOA neighborhood
Thicket Bean takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Very tall growth appears uncontrolled
