A mullein plant grows from between the bricks.
A seed on the wind found the only spot on a brick wall that has enough space to hold soil blown into it and perhaps a few decayed leaves, and sprouts. It’s a metaphor for many things.
No, that photo really is at the right angle, that is a vertical wall, and several feet off the ground as well. A little bit of moss is beginning to grow between the bricks, but a mullein plant? They have incredible tap roots and actually grow quite tall when they flower, but I guess it’s managed to find enough sustenance here to keep it growing and quite green.
Below, the full wall, just to get a perspective on what the mullein has accomplished.
