This statuesque plant is a relative of the sunflower. Although it boasts attractive yellow flowers perched on 3m (10ft) stems, it is mainly grown for its below-ground tubers that can be cooked or eaten raw. Needing plenty of space to grow, this perennial is ideal when planted as a windbreak or screen
Eventual height: 2-3m. Eventual spread: 1m+ (3ft). Enthusiastic plant worth restricting or keeping under control.
