Barclaya Longifolia
Barclaya longifolia
An exotic relative of the water lily, Barclaya Longifolia produces spectacular long, wavy-edged leaves with olive-green upper surfaces and vivid burgundy-red undersides. It grows from a bulb and prefers to be undisturbed once planted. A dramatic focal plant for larger tanks, particularly in Nature Aquarium style compositions.
