Hi jayeeta, I just now saw your question. The first plant hop-hornbeam copperleaf according to sources is considered a weed. With the second, we need to see its flowers to be certain of its ID. Then you will know what to do; keep or toss it. Best wishes! Laura

The first plant does not have any flowers yet. But the second plant has white blossoms? Are they both weeds?

I’m a bit confused on the photos placement. Do you mean the ‘first photo’ is one with a large plant beside those smaller hop-hornbeam copperleaf plants? Can you show the ‘little white flowers’. It will help to narrow down the ID quickly. Thank you & best wishes!
