I grew some wheat grass from seed in large low serving bowl. Wheat grass grows like crazy, I quickly figured out. It had become root bound. It couldn't keep growing because it was limited to the space it was given in the pot. While in the process of moving it to a larger pot, I discovered the amazing root sculpture pattern that was created by the roots. Of course I had to shoot a photo. I was excited when I saw how much the root sculpture resembled the Earth. I thought, "We as humans are also limited to the space we are given on this planet and in life, too."
