Hi, Dr. Hill,
This spring-time wildflower is growing pond-side in sandy-ish soil, full sun in the rural Fall Line. It flowered in late-April (when I took this picture) through May or early June. Now in August, the flowers are long gone and plant has a compact, sprawling habit and its slightly fuzzy leaves continue to be green. I’m also attaching photos of its leaves and dried seed heads.
Thank you, again.
this is in the same family as the Ludwigia, Onagraceae, but this one is an Oenothera, namely Oenothera fruticosa, commonly known as sundrops.
