I live in Northern Louisiana. I discovered this bloom in a flower bed that is full of other bulbs. Have no idea where it came from unless it was in some bulbs someone gave me. I hope I can save it. I will research it.

These get huge rather quickly when sited properly. the spikes in the spring are fabulous accent points but the blooms sadly last only about a week in my Tennessee garden. I dug up a large clump of these this summer and had several plants but they all failed to survive the move. I think once it is established it is best not to move it. Give it at least a five foot diameter circle when planting.
