This last week the flowers of the lily that probably has more names than any other flower popped out of the ground, grew stems about two feet tall, and produced some beautiful flowers. This all happened in a period of about four days. What is your name for the lily in the following pictures?

How about surprise lily, magic lily, nekkid lady, ressurection lily, etc. It is interesting to note that this lily produced leaves early in the Spring that then died away before the flowers decided to pop out of the ground.
