Southern Swamp Lily, American Crinum (Crinum americanum), Amaryllidaceae Family, Texas native, perennial, blooms late spring through summer

Even though it looks like it might be a lily, it is not a true lily because the flower parts are attached above the ovary rather than below, as in a true lily. It spreads by underground stolons and self-seeds. It is found along streambanks and in marshes. It grows in full sun to shade, but blooms better in full sun. It makes a great bog plant.

This plant is growing in a bog environment at my favorite nursery.
