Is this a wildflower or a weed? Of course the phrase "beauty is in the eye of the beholder" always applies to wildflowers. What one person appreciates another might find invasive and vise versa. Then again someone might appreciate it and find it invasive...what do you think? This wildflower is very common in the southeast and much of the United States. I can assure you it is very common in the wilder parts of out yard! I think the pale creamy yellow flowers are very attractive, but in the landscape these plants might take over.
Here are some more pictures that might help you figure it out.

Could this be a clue? Five serrated leaves.
