Wildflower of eastern North America, forming a mound of narrow leaves, and small golden-yellow flowers held on branching stems through much of summer. The flowers are open during the day, closed at night. From previous experience with oenotheras, I expected this to be short-lived as a perennial. Indeed most of our plants didn't get through their second winter, but the one survivor is now a fourth-year plant, and bigger than ever. I like it quite a bit, so I have since saved seed and started a new batch to keep those cheery yellow flowers going around the garden.
