Manroot is a vigorous native vine that produces large, heart-shaped leaves and showy white morning glory-like flowers in summer. This fast-growing perennial can quickly cover trellises, fences, or arbors with its extensive climbing habit. The plant dies back completely in winter but regrows vigorously each spring from its massive underground root system.
In an HOA neighborhood
Manroot 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.
- Extremely aggressive spreader that can overtake other plants
- Dies back completely leaving bare supports in winter
- Can look unkempt without constant pruning
Wildlife value
Host plant for sphinx moths.
The large white flowers attract various pollinators including native bees, butterflies, and night-flying moths. The dense foliage provides good cover for small birds and insects.
