I found this sprig of lambs quarters on the side of the road.
It's amazing that anything could grow in a thin layer of soil over asphalt. It lived in a pot on my deck all summer but didn't grow much bigger.
Then, the following spring, lambs quarters started showing up all over. I put flowers in the pot with this one as a disguise. Even the ever-vigilant landscapers missed this blatant weed hiding in plain sight.
