detailed seed-starting info below

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.

Seed capsules develop lower on the stem while flowers are still blooming above

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
