Missouri Evening Primrose
Details10" tall x 18-24" wide (seed propagated). This native wildflower is renowned for the huge 4" yellow flowers that open each afternoon and close up the following morning. Long blooming throughout the summer months, it keeps going until it feels it has set enough seed pods to retire for the season. Long-lived, it forms a huge underground tuber to keep itself going from year to year. Evening Primrose cascades nicely over rocks and retaining walls. (Botanists have changed the name for this species from missouriensis to macrocarpa).

USDA Hardiness Planting Zones
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).
