This plant came up all on it's own and I have no idea what it is. Can anyone help me?

I believe it's a wild gaura, probably the same as I have around here. I had assumed it was Velvetleaf Gaura...at some time in the past I'd seen a pic of a tall gaura the person who had it said that was Velvet-leaf Gaura. Now that I went to google that name, I'm not sure yet. Will have to look that up more to be sure.

I have pink gaura, Gaura lindheimeri, growing in such large white swath that they perfume the air in the evening. The leaves are much longer than they are wide. The leaves in the photo are too large and wide.

I took this photo during the day when most of the previous night's gaura blooms have closed.

maybe a better photo would help

Gaura has different leaves. They're very willowy.

Oh...here it is! I lost this thread somehow. Okay, not all gauras are willowy. This is what I believe it is...both bluesmaven's and mine. It has apparently changed its botanical name a few times. Anyway, it can get very tall and has little bitty flowers, when open they are a nice pink, but often they aren't open.

well I pulled it up because it was growing outside me bed and I didn't plant it. It was kinda pretty but the flowers didn't open up much. Thanks for your help if it comes back again I might just plant it in the garden and see what happens. I came up at the base of my french drain.
