What kind of plant is this? It's popular around here. This particular one was given to me by my future mother-in-law after my boyfriend's dad passed away. I have had it for 2-3 months and keep calling it "my little tree". Is this even considered a tree? (My guess is "no", but I have no idea.) I know they can get bigger. I repotted this one today. :) Thanks in advance!
