Canna has an interesting family history..
The canna plants are large tropical and subtropical perennial herbs. Canna rhizomes are edible and rich in starch and were once a staple foodcrop in Peru and Ecuador. Cannas may also fall victim to canna rust, a fungus resulting in orange spots on the plant's leaves.
Canna is grown for human consumption in the Andes and also in Vietnam and southern China, where the starch is used to make cellophane noodles.
Cannas are Propagated by seed, or by rhizomes.
Canna seeds need to be scarified and soaked in water prior to planting.
Cannas grow wild and are capable of growing in full sun, part sun, or even shade. They can be grown in pretty much any type of soil.
Cannas commonly die back during cold months, only to leaf out and bloom during warmer months.
Cannas demand regular water during the warm months.
