I just realized that you posted this in the 'Shrubs' forum and not in the 'Houseplants' forum or 'Plant Identification' forum, so I'm wondering if you found this plant as a houseplant or could it possibly be an outdoor shrub?
I still can't tell from the picture.* I'm not sure if another picture that has the light in front of the plant instead of behind it would be helpful for me at this point.* Do you have any pictures with no light behind the plant?

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
