Evening primrose- Oenothera biennis

Here is a link that might be useful: Oenothera biennis

Be careful about planting it. It is extremely invasive.

Thanks for the information! I think it must be the evening primrose. I looked at some photos. Seems like there are quite a few varities, but one of the photos looks like what I may have had. The plant I had was not at all invasive. Thanks again!!

My grandmother had that going in her garden back in Texas. When I visited with her as a kid, we'd make sure to go out at just the right time in the evening to watch them unfurl. I remember being thrilled each time I saw it. I'd love to have them again here in remembrance of those days. She's the one who really encouraged my gardening passion.

Maybe it's O. acaulis. I think that species is pretty dramatic in it's unfurling and gets about the right height.

I found the one my grandmother grew, or it sure looks like it to me: Oenothera erythrosepala. I kept thinking the others I've seen didn't look quite right, but this one was exactly how I remembered, including the touch of red, and the foliage. It was perennial for her, made a mound of foliage all winter, then shot up in Spring to make the 4' or so stalks, with blooms ringing them near, but not at the top.

I think I'll try to find some seeds or plants of that. She had a friend who collected unusual plants, so maybe she got it from him.
