Canna musifolia
Often called banana canna, this plant is grown mainly for its huge, banana-like leaves. Flowering can be sparse in cool climates and is secondary to the foliage display. It thrives in full sun, rich soil, and steady summer moisture. Names vary in the trade; POWO treats Canna musifolia as a synonym related to Canna paniculata, while RHS lists the cultivar ‘Musifolia’. Provide shelter from strong winds to prevent leaf tearing.
