wingleaf primrosewillow, Ludwigia decurrens

Primrosewillows seem to have been named for willows because the have similar lance-shaped leaves, and because they grow in the same damp places. The primrose comes from the traditional yellow flower, but indirectly through the evening-primroses. These are closely related to those. This one was particularly colorful with the red leaves, a benefit from a stressed plant. Red is not typical. Wingleaf is because there is a little leaf-like tissue that continues down the stem where leaves attach. Wingleaf grows in AL, FL, GA, IL, IN(R), KS, KY, MD, MO, MS, NC, OH, OK, PA(E), SC, TN, TX, VA, and WV. Colquit Co GA, 10/19/15.
