Salvia splendens?

true-blue, maybe you didn't see there was a request for more info on the original post. Since it's fallen off the first page, it would be less confusing to post the new photo on this current post instead of the old one. http://forums2.gardenweb.com/forums/load/namegal/msg0619470919678.html?1

Yep, it's a weed. And yes, it's also an evening primrose but that doesn't make it any less a weed!

The best place to post your photos is the Name That Plant Forum on Gardenweb. You won't believe how quickly you will get an id. You can try replanting the ones you think might have been flowers if they haven't been laying out in the sun too long. Best of luck and congrats on you new home.
