Oenothera fruticosa (Sundrops) http://Sundrops.notlong.com 12 June 2007 Oenothera fruticosa (Sundrops) This is my clump of perennial Oenothera fruticosa (Sundrops). I keep the plant contained by digging a trench around the clump. The plant blooms about two weeks, and the vegetation is still a dark attractive green throughout the season.
