This is Tacca nivea, also known as White Bat Flower, Bat Head Lily, and Devils Whiskers. This plant likes to be in the shade with no direct sunlight and it needs high humidity so you can use a rock tray to have standing water around the base of this plant, but not touching the pot itself or getting into the mix. We just want more water in the air around this plant. The bloom is extraordinary with the giant white blossoms shading a group of dangling seed pods, and then the cats whiskers get to be about 2 feet long on a mature plant. Not only does this have a spectacular bloom, but the large deeply veined leaves are also impressive. USDA Hardiness Zones 10 to 11.
