I've just purchased this houseplant because I love its foliage, but I have no idea what it is and consequently I have no idea how to care for it! The backs of its leaves are very purple, while the fronts are striped green and lighter green and they seem to reflect light in a sparkly manner. Also of interest - it seems to drop branches of itself perhaps as a means of propagation. please see the photos I've provided. Any ideas as to what it might be would be greatly appreciated! Thanks!
