 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.

*Also known as Hardy Canna, Powdery Thalia or Powdery Alligator Flag and is a member of the Marantaceae

Great for water gardens and earth bottom ponds. This is not a plant that koi, carp, or turtles tend to target. Great for erosion control. Great replacement for the very invasive cattails.
