Eclectic Red Barn: Camp Lilies

Many years ago, I saw these lilies at a golf course near our camp and wanted some for my garden here. So, with shovel in hand, I asked if I could dig some up.

I have no idea what they are called, but they are blooming all over the camp. Actually, they are not at their peak - starting to fade.
They are interesting because in the spring the plant will produce lovely green leaves, similar to other lilies. Then the leaves die and the flowers shot up with these beautiful pink lilies.

All you have are these tall stems with lilies at the top and no leaves.

This particular bunch is in with lilies of the valley. Oh, how I miss bulbs. It has been so exciting to see the flowers up north. So different from down south.

If anyone knows what these lilies are called, I would love to find out.
