To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
The evening primroses are a group of yellow-flowered plants that range from short “sundrops” to the tall ones like this species. Unlike the roadside weed, Oenothera biennis, O. lamarckiana makes a good meadow plant. Flowers open in the afternoon and are closed by morning. See related species—the ground-hugging, very large-flowered Missouri Primrose, O. missouriensis and the famous pink-flowered Showy Evening Primrose, O. speciosa.
