We're not able to identify the plant pictured as it does not have enough features to evaluate. Flower traits can be very important to plant ID, but sometimes foliage characteristics can be sufficient, though this plant hasn't developed enough yet for that to be used for narrowing-down ID. Habitat and the conditions in which a plant is growing (wet, dry, sunny, shady, acidic soil, alkaline, etc.) can also help to narrow-down a list of possibilities when foliage looks similar between several species. If you choose not to remove it and let it grow for a while longer (perhaps a few weeks), we can try again if you can send in more photos.
