Sorry to confuse you - so many plant names use for different species, especially "lily"!! I was referring to Hymenocallis. Nothing like those. There are many varieties, apparently all white, usually with orange tipped stamens. Spectacular and strange looking. You can see why they are called spider lilies (only 6 "legs" though
). A resort we go to in Jamaica has them, which is where we I first saw them, so probably Hymenocallis Fragrans.
