Missouri Evening Primrose is a showy native perennial known for its large, lemon?yellow flowers that open at dusk and glow through the night. Each bloom is silky and delicate, often spanning several inches across, and rises above low, spreading foliage that hugs rocky or sandy ground. The flowers fade to a soft peach as they age, creating a beautiful color shift in prairies, glades, and dry open meadows. Bright, drought?tolerant, and unmistakably striking, Missouri Evening Primrose brings luminous beauty to sunny native landscapes.
Overall height at 0.5–1 foot.
Missouri Evening Primrose serves as a host plant for several native moth larvae, and while butterfly use is limited, species associated with dry, sunny habitats may occur where it grows. No butterfly species are confirmed to use Missouri Evening Primrose as a primary caterpillar host, though butterflies such as the Painted Lady Vanessa cardui and the Gorgone Checkerspot Chlosyne gorgone may be found in similar environments. Its night?opening flowers attract nocturnal moths, bumblebees, and early?morning pollinators, providing an important nectar source during warm summer months.
Historical accounts note that plants like Missouri Evening Primrose were used by Indigenous peoples and early herbalists in teas and poultices for minor ailments, particularly for skin and inflammation?related concerns. These uses reflect cultural tradition rather than modern medical guidance and should be understood as historical context rather than recommendation.
Missouri Evening Primrose provides meaningful wildlife value by supporting nocturnal pollinators, enriching pollinator diversity, and contributing to the ecological structure of prairies and glades. Its drought tolerance, long bloom period, and luminous flowers make it a valuable species for sustaining beneficial insects in sunny native landscapes.

Missouri Evening Primrose grows best in full sun and prefers dry to medium, well?drained soils, thriving especially in sandy, gravelly, or rocky sites typical of glade and prairie habitats. It tolerates drought, heat, and nutrient?poor soils, declining only in heavy, wet, or compacted conditions. The plant forms low clumps and spreads slowly by seed, persisting best where drainage is excellent and competition is light.
Please note that Riverside Native Perennials (RNP) only ships our potted “35” product via USPS, UPS or FedEx. We generally can have your plants boxed up and ready to go within two or three days. All other products including our flat of plugs, 1-gallon and 3-gallon containers are only available for nursery pick up in Delaware, OH. For large orders of any of our products we can arrange shipping at an extra cost. Please contact the nursery for additional information.
It’s important to note that when we send plants to you, presentation is everything! We recognize that you’re expecting healthy plants to arrive safely on your doorstep ready to be planted and that is what we’re selling. Further, we want you to know that while we are a fully licensed and inspected perennial nursery in the state of Ohio…we are in Ohio! That means we are subject to Ohio weather. The average frost-free date for our area is May 15. So even though you may live in Florida or California your plants are growing under Ohio conditions and we do not heat our greenhouses due to the expense. Our plants may be slightly delayed but again it’s because we’re in a Zone 5 area. Because we ship nationwide, we ship plants at all times of the year. If it’s winter in Ohio, you’ll be getting dormant plants. If it’s spring or summer in Ohio, you’ll be getting plants of various sizes that are actively growing. Plants shipped during fall in Ohio may be dormant or may be heading towards dormancy. This is all natural and we do not try to modify or prolong the growing season other than to grow them in an unheated greenhouse. Even in an unheated greenhouse our plants are much further along and growing well early in the spring than if they were planted outside in Zone 5. If you would like additional information about sizes for a particular species, please contact us via email.
In 2021 RNP partnered with a shipping professional to design and develop a shipping system that could reasonably be expected to survive the USPS mail room and transportation process. After several design sessions and going back to the drawing board on more than a couple of occasions we created a shipping box system that, to us, is bulletproof. It is strong, lightweight and, to date, has not failed in shipping thousands of packages of plants to all corners of the country.
Once selected from our greenhouse benches, your plants are placed into a small plastic bag to maintain moisture during shipping. To keep the soil in the pot we created a cardboard insert that perfectly fits into the top of our 35 containers. The insert has a cutout that surrounds to plant stem without damaging it. The plastic bag and insert are secured by two rubber bands. Each bagged plant is then placed into an individual corrugated cardboard box which perfectly fits the 35 container, and which locks it in place so that it will not move during transit. Four individual boxes are then placed into another, even heavier duty corrugated cardboard master shipping box. The whole effect is that of double boxing your plants. They are safe and secure for the long trip to your home landscape!
The system only works with 4 individual boxes being packed into a single master shipping box so we encourage you to buy four plants or a multiple of four plants. You can buy less than four plants but we will need to send all the cardboard for four plants in order for the shipping system to succeed as designed.
