It's either Lilium superbum or L. michiganense. If it is L. michiganense the veins on the undersurface of the leaves will feel very rough. I'm leaning toward that one since the style appears to be similar in color to the petals and the anthers don't look very long. In L. superbum the style is usually greenish and the anthers are relatively longer.

Nice little suprise there. I believe you could get rid of it if you dont want it there, just connect the inlet and outlet tubes together in some way. Otherwise just leave it, knowing its there. There should have been a door there to access it instead of boxing it in. Make sure the T&P valve tube (the copper pipe hanging down) is not capped off. It kind of looks like that but it could just be the end of a water heater connector. If its capped off you have a potential pressure cooker bomb in your house if the water heater malfunctions.

Already have several Eastern GST in the works in 3 stages; 4 chrysalides, 2 cats on rue, and many eggs out on the orange and trees.

Well thank you again everyone! I'm in Florida and mostly planted foliage that stays colorful year-round. Like I said, my house isn't grand or anything but it was a neglected foreclosure when I bought it. I still need a tree somewhat off to the side but one that will not grow so wide as to block my light in the art room. So far I haven't seen anything that I like. I will post some pictures tonight. Right now I'm doing some stepping stones in the back to mark a path so the guys who mow will stop trampling the things I have planted. Breaks over now and not much light left so gotta go.
