Plant of the Day, Galinsoga ciliata, Quickweed or Shaggy Soldier
I observed dozens of this plant within a wetland that I was monitoring. it is a fast-growing summer annual, and all parts of the plant are edible and nutritious. It is considered a weed of vegetable crops and is identified via its tiny flowers of five parts, having three toothed rays and yellow center disks. The stems and leaves are hairy/shaggy.
The plant is native to Central America (makes sense that I saw it in Montgomery County, MD), and is considered an alien invasive within the United States. The plant has a preference for moist conditions.
