Canary yellow, mildly fragrant, 3 inch wide flowers are produced in great numbers over dark green, lanceolate leaves from early thru midsummer. Following the substantial blooms, seed pods are produced which are beautiful in dried arrangements.
Genus Notes - Oenothera
Although they belong to the same genus as Evening Primroses, Sundrops bloom during the day, brightening the garden with clusters of four-petaled flowers. Plants are easy to grow, easy to maintain, and very tolerant of heat, drought, and poor soil.
Oenothera will maintain a healthy compact form in poor, well-drained soil and full sun. In more fertile soils, it tends to spread rampantly. Evening Primrose is perfect for covering gravelly banks and other areas where the soil quality is poor. Hot, dry conditions are no problem for this plant.
