*This plant sits in a self-watering pot in an east-facing window. It is three years old.*

This is the one plant that grew from a pack of 10 seeds for a Grow-Your-Own-Bonsai box. I think it was meant to be a joke, but here it is! (Although it does not look like the picture on the box!) It is a simple plant. I have enjoyed watching it grow and cheering it on when it was very small. Every Christmas, I hang a bright, red, shiny bauble on it.
