Variegated Canna lilies exhibit leaves with a mix of colors, typically green combined with other shades like yellow, cream, pink, or even red. The variegation pattern can be stripes, blotches, or other irregular markings, creating a striking visual effect. This makes them popular ornamental plants for gardens and landscapes, offering a vibrant display of foliage and flowers.

Color Variations:

Variegation in Canna lilies can range from subtle to bold, with various combinations of colors.

Pattern:

The patterns are not uniform and can vary even within the same plant, adding to their unique appeal.

Popular Cultivars:

Some popular variegated Canna cultivars include 'Tropicana' (with orange, pink, and red stripes) and 'Bengal Tiger' (with yellow and green stripes).

Growth Habit:

Like other Cannas, they grow from rhizomes, can reach considerable heights (3-6 feet or more), and are often grown as annuals in colder climates according to Wikipedia.
