Answer: Hmm, it's tough to identify plants without seeing them, but I wonder if what your neighbor has is a Spider Lily (Lycoris). It is a bulb plant and it has narrow, strap shaped leaves similar to the typical houseplant. It does flower in late summer/fall with a flower head that has very thin petals that curve upwards. Just to make things more interesting, there is a variety of spider plant (houseplant) that has plain green leaves without variegation! Perhaps you could look up Lycoris in a reference book at your local library, or find a photo of it online and compare it to your neighbor's plant. Good luck!
