Chamomile

Thanks Melissa! From the second photo, the leaves look less like chamomile, and seems to either be scented or unscented mayweed. As you might imagine, the best way to tell these two apart are to give them a sniff! Scented mayweed has the most delightful smell, scentless doesn't smell of anything :) Let us know, and I hope you can get some more detailed shots of the leaves!

Beautiful! From what I can see of the leaves, this is a kind of mayweed, from the genus Matricaria. Do you have some other photos of the rest of the plant? It will help us ID exactly what kind it is, chamomile (from Monika's comment) is a possibility, but it could be others! Did it have a scent? Great photo though!
