Brought it inside to cool temperatures and pretty low light (an east window, with lots of other plants blocking the sun) and it has kept on growing -- seemingly unfazed by me forgetting to water it. I'd grow it for the bold, vase-shaped, yellow-striped foliage alone, but come mid-winter, it thrilled me with a flower spike covered with bright pink bracts:
