Cannas are large plants and do well during the heat of summer.
They may be started indoors but large pots and lots of space are needed. Flower colors are white, yellow, red- orange or pink. Some staking may be necessary as is the removal of dead blooms. The rootstocks are planted after the soil has warmed. When the tops are frosted in the fall, cut back to within 6 to 8 inches, and dig the rhizomes.
