This is not a "bonsai tree." It's a seedling in a nursery container (looks like a one-gallon). You can make it into a bonsai. Plant it in the ground, let it grow for 3-5 years, chopping it back from time to time, then you'll be ready to lift and shape it and consider when to pot into a bonsai container. There's plenty of information on this forum about growing out immature stock. Spend some time researching so you'll know what to do with this specimen. For now, it's just an elm in a pot. Oh, and you need to get yourself about 50 more trees so you won't be tempted to "bonsai" this one. Trees don't like too much love. Good luck!
