Maybe something you've never seen before...
OK, probably not. But unusual, I think so.
We have a golden weeping willow (which, by the way, has never weeped and its 5 years old) that seems to be a mutant. It has a separate completely different tree growing out of it. We bought it from Home Depot and noticed the "other" tree right away, but didn't really investigate for a while. We thought it was probably just a seedling growing in the same pot. Then, when we did, we quickly realized that it is actually a part of the willow. Very strange. I have been meaning to take a pic and get input from you guys on what you think is going on here, but, well, procrastination and all. Anyway, finally was able to get a few pics. What do you think?
In this pic, you can see the other guy peeking out of the top of the willow
