A shorter cousin of the towering Common Evening Primrose (Oenothera biennis), this "front yard native" species presents a tidy habit and cheery bright yellow, fragrant flowers suitable for a front-yard garden. Later in the season, the plant can look a little run-down; position it behind other plants of similar height, such as Canada anemone, that can act as a screen. Attracts long-and short-tongued bees and butterflies. Spreads readily if given good conditions. Blooms May to June. Full to part sun. Medium-wet to medium-dry. 2'.
