Guess that flower game

Ok so below are some pictures of a flower that has grown in my yard. Upon further inspection I have about 30 or so bulbs that I beleive may be this flower they are all just now starting to grow. My question is what in the world is it?

Now this is where you all come in. I am sure someone knows what this flower is. Albert called it a spikey flower. Sarah called it a dragon flower or something to that effect. I have no clue what it is. So if you know what it is then maybe you could tell me how to take care of it. The part of our yard you are looking at is the back. That nice tree is in the middle of our brick patio. Yep right in the middle. It use to be almost completely covered in ivy. I got most of the ivy out but the dumb stuff won't quit growing. it is all over our yard. I like morning glories a lot but we also have those all over our yard. It is hard to keep up with. It grows on the bushes and the fence and all kinds of places I don't want it. I think I could pick ivy and morning glories everyday about. Ok so now it's your turn to write and tell me what that flower is. It is very unique. I haven't decided whether I like it or not.
