With water, it will grow and grow

I walked by these two homes which were next to each other. They both decided on some interesting landscaping ideas. The one on the left is for a tree. Don't get me wrong, I love the idea of getting a tree to grow, but this tree is literally 3 inches tall and they have decided to mark off the tree's territory. I can't wait to see this tree reach 6 feet tall in 25 years. The one on the right is my favorite - they have planted flowers around this tree...wait, thats not a tree. It is a pipe sticking out of the lawn. Yet, they are treating it as a tree. I will be curious if this pipe ends up growing and if it blooms in the spring.
