I've heard of time in a bottle and even a ship in a bottle, but I have never seen anything like this:
A tiny fern is growing inside this bottle. The bottle is part of an edging to part of my garden. It's an idea I borrowed from a friend and I love it. The "fern bottle" is the last one on the right of this picture.
But back to the fern. It has grown inside this bottle spontaneously. The closest fern in the garden to this bottle is about 2 feet away. Nature continually amazes me.
