Missouri Evening Primrose blossoms open in the afternoon, greeting you at the door when you get home from the office. They remain open into the next morning, when you leave the house again. What a lovely way to start and end your workday! The large, four-petaled flowers are brilliant yellow—like pure sunshine—and they give off a light, sweet fragrance. Perfection. Evening Primrose forms a low, spreading mound and makes a charming border to a sunny planting bed. It’s especially nice spilling over a retaining wall, where the extra height will bring the gentle fragrance closer to your nose.

The Story

Our country is blessed with some of the world’s finest wildflowers—flowers that have fortunately found their way into our gardens as well. Missouri Evening Primrose is one of these special Spirits; from late spring through mid- to late summer, it lights up American prairies, gardens and roadsides. You’ll find it in the wild from Nebraska to Illinois and south to Texas and northern Mexico. Missouri Primrose enjoys dry, rocky areas and will thrive with a minimum of water and fuss in your landscape. Make it part of a mixed border by your entryway, or include it in a native plant restoration, dry meadow, or rock garden.

The Details

Missouri Evening Primrose has cool, wavy foliage that comes up late. Because of its late arrival in the spring, it makes a good partner for early-blooming bulbs like Crocuses. The bulbs will give you blossoms to enjoy in early spring, and their flowers and foliage will fade away in time for Evening Primrose to strut its stuff.

How to Grow

Although Missouri Evening Primrose is native to the southern Plains states, it’s extremely adaptable and can be grown in many other regions of the U.S. The two things it requires wherever it's grown is sunshine and good drainage. Free-draining soil is especially important in areas with wet winters, as the roots are susceptible to rotting in those conditions. Evening Primrose sets large seedpods in late summer (they make interesting additions to dried arrangements). You can scatter the seed to encourage new seedlings to appear. This Spirit doesn’t like to divided, so scattering seed is the most effective way to make more plants.
