My very first tree was a pomegranate from a local garden centre which I killed in its very first winter.
This is a picture of one of my earliest trees after that, a ficus natasha (or at least that's what it was labeled when I bought it) at some early point in it's training. I eventually got tired of fighting a loosing battle trying to get it to thicken up and bud back and gave it to my sister. She now grows it in a large patio type pot in her living room. Its become quite a bush and is much healthier and happy than I was ever able to get it.
