Or Wood's Blue Goddess. Post pictures of the pads, that'll help. But since you can't trace the provedence of the lily it really should be called "un-name pretty blue lily, that might be a Colorata or Wood's blue Goddess, but don't quote me on that". Guessing at the name, and then passing the lily along to other lily lovers is one way so many incorrect lilies end up on the market.
