Lilium lancifolium would be the most likely one in N. A.

Here is a link that might be useful: Lilium lancifolium

I can always count on you for an answer. lol Is this invasive like the common ditch daylily? I know they are different types of lilies.

I've never seen it naturalized but it is listed as invasive.
BTW Daylily buds are also edible and I love them steamed
or stir-fried. Too bad they don't naturalize in this area.

They carry a virus that infects other Lilium. The amount of stem bulbils produced is overwhelming. In my former garden I tried to remove and throw away as many as possible to keep the population down. I won't grow it in my new garden.

I know that the buds are edible and occasionally make them. They are also great stuffed (I usually use spinach and feta or other cheese) then dipped in a tempura batter and deep fried. I do the same with squash blossoms. I have no idea what they do with the bulbs. They don't look particularly appetizing though. lol

Thanks for that info Carol. I'll keep them in the pot for now. Do all the bulbs carry the virus? If not how can you tell if they are infected?
