White bat flower (Tacca integrifolia).

Temperature and Humidity
The batflower can grow outside all year in its hardiness zones, but it does not do well once the temperature drops near freezing. It prefers temperatures of the tropics in the range of 70 to 90 degrees Fahrenheit. It also must be protected from wind (including indoor air vents), which can damage foliage and burn the plant. Furthermore, the batflower thrives in humidity. In an indoor pot, its humidity level can be increased by regularly misting the plant or placing it on a pebble-filled tray of water.
