I bought this as 'Christmas Star', but when it flowered, it's obviously not! I've been given a tentative suggestion of 'Pajama Party', but I'm not sure. All the pictures I can find of that cultivar show the white pretty evenly matched over all the petals, whereas on mine, the top petal just has a white/green tip, and the white streaks get bigger as the petals go toward the bottom of the flower.
