Oenothera caespitosa Nutt.
Tufted Evening Primrose, Gumbo Evening Primrose, Gumbo Lily, Fragrant Evening Primrose, Tufted Evening-primrose
Onagraceae (Evening Primrose Family)
Synonym(s): Oenothera cespitosa
USDA Symbol: oeca10
USDA Native Status: L48 (N), CAN (N)
Rosettes of oblong leaves with pointed tips subtend Tufted Evening-primrose’s 4-6 in. flower stalks. Each large, white flower has four, heart-shaped petals and eight yellow stamens. The flowers open in late afternoon, close the next morning, and wither to pink or red-violet. Lateral roots may give rise to new perennial plants.
Tufted Evening-primrose is a member of the evening-primrose family (family Onagraceae), which includes mainly herbs, rarely shrubs or trees with often showy flowers. "Primrose" ultimately derives from a Latin word meaning "first" and the true primroses (Primulaceae), unrelated to evening-primroses, are among the first flowers to bloom in the spring. Apparently in the early 1600s when an eastern United States species of Oenothera was being described, its sweet scent reminded the botanist of wild primroses of Europe. He gave the name to those plants and it stuck.
