Canna CANNOVA plants make one think of Mediterranean, subtropical or tropical countries and regions, the beach, warm nights, flowerbeds, the sun, warmth and good times. The CANNOVA series, with its outstanding garden performance and profuse flowering until the first frost, adds a tropical touch to any outdoor space, whether it’s a cool or warm Summer! When the flowers fade or turn pale, they can easily be removed. This makes the plants look more attractive and stimulates the initiation of new buds and flowering. Place your CANNOVA in a sunny to semi-shaded and sheltered place. Cannas have large leaves; if subjected to wind, their leaves can become damaged and turn black.
