Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Missouri evening primrose is a sprawling perennial that typically grows 6 to 12 inches tall and 12 to 18 inches across, though through reseeding, it can spread farther. It has singe, 4-petaled, mildly fragrant, bright yellow flowers which open for only one day (usually open late afternoon and remain open until the following morning). Flowers are generally upward-facing, but sometimes rest on or touch the ground. Long spring to summer bloom period. Flowers are followed by somewhat unique, winged seed pods. Narrow, lance-shaped leaves. Stems are sometimes a vivid crimson red. Grow in rock gardens, perennial borders, parkstrips, and evening gardens. Many cultivars available.
