Dennis - The first photo set is definitely not a Hymenocallis. There would be a clear bulb with the roots only emerging at the base and the arrangement of the foliage would be quite different as well and not whorled. It looks like the early season shoots of a Sagittaria spp. to me, but not sure which species. I would guess the second mystery is a sedge, likely Carex sp. but I would need to see closer shots of the exposed roots, rhizomes and foliage. The Iris look similar this time of year-but that does look like Iris tridentata! Pond muck! so lucky ;) Alani Davis
