Oenothera macrocarpa ssp. fremontii Evening Primrose
With large yellow flowers this Evening Primrose, Oenothera macrocarpa ssp fremontii, stuns in the garden all summer long. Huge flowers contrast spectacularly against its extremely narrow foliage. Very similar to the Missouri native Evening Primrose, except the foliage is showier with its thin shape and slight silver shimmer. Native to Kansas and Nebraska.
Use Evening Primrose in perennial gardens, rock gardens, native gardens, pollinator gardens, rain gardens, as a ground cover, edging, and in banks and slopes.
Plant Evening Primrose in full sun to light shade. Very easy to grow, they are not particular about soil as long as it’s well-drained, and will tolerate poor rocky soil. Due to its long tap root it does not like to be moved.
