My grandmother recently got a plant that we have no idea what it is. She got it from her sister's house after her sister passed away.

It is a medium sized plant with a thick Snake plant like leaves with spines along the edges. The leaves have gray mottling on them much like a Snake plant. There is a large pinky spiny blossom growing from the center of the plant.

Any help identifying this plant would be greatly appreciated.

Thanks,
Mandy
