Powdery Alligator Flag (Thalia Dealbata) – 3 Gallon Pot

Other Common Names: Hardy Water Canna, Powdery Thalia

An eye-catching addition to a water garden or bog garden, Thalia dealbata, commonly called Powdery Alligator Flag, is a marsh or aquatic perennial that loves life on the wet side. It features a 3 to 4 feet high clump of large, paddle-shaped, canna-like blue-green leaves to 18 inches long from which rise numerous long and arching flower stems to 6 feet high bearing panicles of some of the most unusual but pretty lavender-purple flowers in summer. The foliage looks like it’s been is dusted with white powder, hence the common name. Though its a North American Native hardy in USDA Zones 6-11 you’d swear its origin was the tropics. It really adds a tropical flair to water gardens or in those sunny areas of the landscape where the soil never dries out.

A regionally hardy plant native to the wetlands of the southern United States, it can endure mild winters, but roots must be submerged deep enough not to freeze. For use in your water garden, plant in a one or two gallon size container and submerge the pot 2 to 6 inches below the pond water surface during the growing season. In USDA Zones 6-8 it’s best to submerge plants in 18 to 24 inches of water during the winter months.
