Rough and tough American natives, the many varieties of Evening Primrose are grown for their showy yellow-pink or white cup-shaped flowers. Their petals often have a satiny sheen or delicate shading which makes them irresistible. True to their name, some Evening Primrose flowers open only in the evening or on cloudy days. Varieties which open during the day are called Sundrops -- you will see some referred to as Evening Primroses. Use in wild or meadow gardens and in the front of flower borders. Given full sun, most require little care. Plants sold throughout the growing season, and seed is easy to germinate.
One of the most beautiful varieties, its elegant, lemon-yellow flowers, which grow up to 5 inches wide, are followed by winged seed pods. Good in rock gardens.
