White morning-glory is a native annual vine that produces small white trumpet-shaped flowers from summer through early fall. This climbing plant can reach up to 10 feet tall and spreads moderately, making it useful for covering fences, trellises, or other vertical structures.
In an HOA neighborhood
White Morning-glory 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.
- Vigorous vine growth can appear uncontrolled
- May reseed aggressively and spread beyond intended areas
- Can look weedy when climbing on structures without proper support
Wildlife value
The flowers attract bees, butterflies, and night-flying moths throughout the growing season. Seeds provide food for birds in late fall.
