Looks to me like one that I have called Hidden Ginger. I've had it for years, but this year is the latest that it came back, ever.

Another vote for hidden ginger here - I have some blooming like that right now.

If the blooms appear before any leaves, then it's probably Curcuma Elata.

Here's another link that has pics of several Curcumas, when you have some foliage to look at you will have a better chance of ID-ing it. I think mine is Curcuma zedoaria.

The leaves look just like the pictures of Hidden Ginger.
Curcuma Elata looks so much like Hidden Ginger.
My plants,some times the leaves emerges before the flowers ans so time the other way. Last year,only the leaves emerged,not the flowers. I have them in shade and full sun. They do well in both condition. They also multiply

Thank you,all for helping. I love the foliage and the flower.
