Plant Plants, anywhere/everywhere

Facebook reminded me that 3 years ago I decided to plant new seeds and give a home to struggling house plants in this abandoned flower bed on my block. Today it's a towering mass of trees, vines, and other growth. It's been blocked off by construction materials so I can't see it fully but I haven't watered it in 2.5 years and yet it flourishes with new additions still finding their way there, maybe through birds dropping seeds or species spreading from the surrounding area? The bottom line is that we should be planting stuff everywhere because in this climate it will proliferate with very little care.
