This lily, perhaps Crinum, was photographed in Sunnyvale, California in August, the flowering scape without any accompanied leaves. Pl. help in ID
singhg45 and vngarden - they both look like Amaryllis belladonna to me - differences in pics are due to lighting and/or color balance processing of the camera.
Amaryllis belladonna alright. They naturalize in my area and I have lots of them. They don't like to be transplanted though, so if you move them don't expect to see them for awhile.
