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.
