The pics are pretty "fuzzy" lacking detail. The tall lilies appear to be American lotus, maybe not since the pics are poor quality. Are there in the fall brown flat cone type heads where the tall flowers on stems were, that have rattling balls in them? The 3/8" - 1/2" dia balls are seeds and produced by lotus.

Some of the flowers looked like spadderdock lily.
