Years and years ago my mother visited her uncle, my great uncle, and took away some Japanese maple seedlings that were growing in his flower beds. She gave me four of them and because it was still cold outside where I was I put them in my grow tent. Well lo and behold about a week later a little pot plant popped up out of one of the cups. I was like... HEY! That's not one of mine!
lol
Interesting way to find out your 87 year old great uncle is a stoner
