Also known as large-flowered evening primrose, magic primrose (Oenothera glazioviana) produces a basal rosette of nondescript green foliage the first year or two. (Be sure to mark the rosettes, because it is easy to mistake them for weeds–I speak from experience!). When the plant is ready to bloom, it sends up 3- to 5-foot-tall flowering stems topped with pointed buds that unfurl quickly into fragrant, yellow flowers at dusk: a magical experience to enjoy each evening through much of mid- and late summer. The blooms remain open through the night and close the next morning. Full sun to light shade. Magic primrose usually acts like a biennial but can be a short-lived perennial, particularly if you cut off the top of the stem, with all of the developing seed pods, as soon as there are few or no more unopened buds at the stem tip. Zones 4 to 9.
Harvested in 2019 for the 2020 growing season. At least 20 seeds.
