Hi Lucy! It's a dwarf lemon but I don't know if it's grafted or not. I don't see any graft lines so I'm guessing it's from a seed or cutting. The pot is an 8 inch pot. I bought it in a 7 inch pot but it was root bound and the soil held way too much water so I repotted it into a larger pot and with well draining potting mix. I said pretty direct sunlight bc it's indoors, but it's in the corner of my living room when it receives both West and South facing sunlight through the windows. I've included more pictures of close ups as well! There's one branch that is longer and juts further out from the tree than the rest.
