Tacca chantrieri produces the most unusual and striking flowers. The flower is black with long sinister tentacles hanging down wards. Its leaves are broad and about 40cm long. They are quite hardy once grown up but need to be nurtured over their first winter in cooler climates than tropical. Give your Bat Plant a real well drained potting mix with good moisture in the summer but keep just moist in the winter. They do not like the cold frosty weather outside so you will need a warm spot, under shelter or inside. Keep it under light to heavy shade.
