Here's another pic of the same plant.

Here's something else. This little bit of a thing volunteered itself in two or three places in my yard. It looks like something that might have a bulb that I could dig up when it's done blooming and stick it in the garden?

Thanks! It looks like the collective genius of everyone is pretty popular :)

First looks like Datura (D. inoxia perhaps?).

The bulb appears to be a spider lily- Lycoris radiata. Never grown it, so will let others speak as to best time to transplant ;-)

Agree the top pictures look like a datura or perhaps brugmansia. No idea about the second.

The first one is definitely Datura, and I don'tknow if it is perennial in your zone, but it's a ***prolifically*** self seeding annual in colder climates. Be careful and make sure you deadhead it if you don't want thousands of volunteers. I have them coming up everywhere, even when I do deadhead them! Also, don't sow too many of the seeds. It seems to me as if every single one of them germinates!

Wow, thanks everyone. I knew y'all were geniuses! That was fast!

So I'm a bit sad about the datura. After reading some about them, on top of the fact that they only bloom at night, I don't know if I'll plant any of the seeds. I've had my eye on getting a brug for a quick minute, though, and now I want one even more. Maybe I'll just do one datura. I don't know.

What I read about the spider lilies is that they bloom in late summer, stay green through the winter, and fade back in the spring. How peculiar! Unfortunately that means the best time to transplant them will be in the spring when they fade back, and my husband will surely get them with the lawn mower long before then. Anyone try to transplant them in the fall? There's a few clumps of them near a fence in my backyard also, and I'd love to put them in a new home, safe from the lawn mower blade. I wonder how these randomly appeared in the first place.
