 Thalia Dealbata (aka, Hardy Water Canna)

Thalia Dealbata or Hardy Water Canna, is a lovely aquatic plant with large, handsome, blue-green leaves. In mid-summer, taller spikes of purple blooms emerge in clusters. Foliage grows to 3 feet tall in height and flowers bloom on taller stems. Native to wetlands in parts of Nebraska to New York and through southern United States. Beautiful blue-green foliage is canna-like in appearance with interesting, purple flower spikes that grow taller than the foliage. When planted in large containers or planters, these plants make a striking focal point adding beauty and grace to your water garden setting.
