Question
Hi I have this plant growing next to my sidewalk. It is the second year in a row I've seen it growing. I've also seen the same plant growing in the neighborhood, in Reading MA. Can you identify it for me? I've yet to see any flowers, but it grows rather leggy, and the green begins to turn red as the plant is stressed (also toward the end of the growing season). These photos were taken on 8/18/2024.
Answer
Dear Stephan, you have photographed a species of Bidens (beggar-ticks). It is likely Bidens frondosa or Bidens vulgata, but we will need flowers to determine which species it is. I hope knowing the genus is helpful. Best wishes.
