Oenothera macrocarpa (formerly O. missouriensis)
Onagraceae (evening primroses)
Missouri evening primrose is a sprawling herbaceous perennial with multiple stems that trail along the ground. Often seen festooning the tops of bluffs and rocky road cuts. Blooms May through August. Flowers are solitary, very large (up to 4 inches wide), 4-petaled, and bright lemon yellow. Often there are many blooming at once, making this a very showy plant. The flowers last only a day, usually opening in late afternoon and staying open until the next morning. Leaves are narrow and lance-shaped.
Height: to 12 inches; spreads to cover 2 feet in diameter.
Where To Find
Statewide, but especially in the Ozarks south of the Missouri River. Cultivated statewide.
Habitat and Conservation
Usually found on limestone glades, bluffs, and rocky prairies in the Ozarks, but this favorite hardy native wildflower is also a popular plant for gardening and in roadside beautification projects.
Common. This species was formerly called Oenothera missouriensis, and some sources still use that name.
Missouri evening primrose is a favorite garden plant, particularly in sunny rock gardens, borders, and meadows, where it requires little care. It doesn't do as well in wet and poorly drained soils.
Flowers that open at night are usually pollinated by night-feeding bees and moths, and thus supply nourishment to those species. Some moth caterpillars feed on evening primroses as a main food plant as well.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
