Full or partial sun. Canna is a large-leaved herbaceous perennial with warm-colored flowers and leaves resembling its close relatives, banana and ginger. Many cultivated varieties are available. The name “canna” originates from the Latin term for “reed.” Like reeds, canna naturally grows in fairly wet settings.
Canna is big and sloppy; frequent grooming and removal of spent leaves can keep it looking fresh. It freezes down to the rhizomes during extreme cold.
Canna spreads aggressively along streams and rivers.
