Water Hawthorn is a deep-water marginal plant. We are shipping a growing plant currently. This attractive plant grows from a small bulb and unlike other potted, plant prefers cool water. The dark green leaves are long and narrow and float on the surface. It blooms in the spring when the waters are still cold, and then again in the fall once the water temperatures have fallen. This plant will go dormant during the summer months, so don't accidentally discard it mid-summer, as it is dormant and will begin growing again as the water cools in the fall. Many areas in the south are not suitable for this plant.
