The green tangle you see at the top of the photo are baby chives. These shoots are the spring run from a chive bin that was established in 2010, but every other form of plant life you see showed up on it's own. I don't know what kind of baby conifer tree is in the lower left corner, but I do know the wee red floppy plant behind it is a variety of lettuce known as Red Deer Tongue. I looked into, "where moss comes from,?" online and apparently its 400-500 million years old. It totally must have blown in as a spore, or the spore was already in the soil when it was delivered to us. Instead of roots it has, "rhizoids," tiny hair-thin filaments that anchor the moss to the soil. And it gets everything it needs to live from the air and water. Whoa. Sharpie for scale.
