Oenothera caespitosa-Tufted Evening Primrose

Tufted Evening Primrose is perfect for moonlit gardens. From spring through late summer it produces masses of huge white flowers that open in the late afternoon. They close in the morning as temperatures heat up, fading to pink. The fragrant flowers are at least 4 inches in diameter, and stand out against the large dark green leaves. Tufted evening primrose occurs across the western United States, from 4500 to 7500 foot elevations, and is hardy to -20 F. It also handles summers in the low deserts, but needs excellent drainage. USDA Zone 5.
