The photo's pretty small, so it's hard to say. It looks like geranium foliage in front, with a different, taller flowering plant behind it. It might be helpful if you can post larger closeups of both the foliage and the flower.

It doesn't seem to branch like the fennel photo you mentioned. Here's a photo of the whole plant...still growing, no flowers...will check on any odor it may have... soon... This post was edited by mjp13 on Sat, Oct 4, 14 at 15:17

Thanks for the clarification. This is why I normally use Latin when talking plants. Too many similar common names. Floral_UK, I was under the impression that some other weed strains have developed a resistance to round-up since GMO seeds are marketed as Roundup resistant themselves, there by encouraging farmers to use much heavier concentrations of this pesticide than they normally would.

A location would have been useful. However, Abutilon indicum is a tropical plant. It has never been reported as escaped in the US, and has much smaller leaves than those shown in the photo. That looks like typical A. theophrasti to me.
