The Canna lilys (genus Canna) are tropical and subtropical summer-blooming plants with broad flat leaves that grow out of a stem in a long narrow roll and then unfurl. The plants grow over five feet tall but are most often around three feet tall; they often bloom red, yellow, orange, or any combination of the three in spots or variegated; the leaves are typically green but may be a deep maroon instead. In botany, a leaf is an above-ground plant organ specialized for photosynthesis. ...

The canna may rot if left unprotected in freezing conditions, but it is a perennial plant in temperate zones; it does well with moderate water in well-drained rich or sandy soil and is largely free of pests. In areas which go below about -15°C (5°F) in the winter, the rhizomes (horizontal roots, not unlike those of a potato) can be dug up before freezing and stored in a protected area for replanting in the spring.

The flowers attract hummingbirds. The plants sometimes fall victim to Canna leaf rollers, or Brazilian skippers, the larval stage of a butterfly that cuts the leaves and rolls them over to live inside while pupating (the lesser canna leaf roller will sew the leaves shut before they can unfurl). Affected leaves can be cut off and destroyed or unrolled and cleaned (removing the caterpillar), though some gardeners prefer to use Bacillus thuringiensis, insecticidal soap, or the chemical malathion to kill the pests. In areas with a freezing winter the leaf roller is not typically a pest.
