Excellent form of this sprawling Rocky Mountain native evening primrose. Super silver leaves are held upright on a spreading plant. Beginning in June huge 3″ wide shimmering, luminous light yellow fragrant flowers appear almost daily for months. Full sun and rich, well drained soil with little summer water once established. Excellent performance in rock gardens as well as parking strips. The flowers are a really good shade of yellow and harmonize brilliantly with the silver foliage. Winter deciduous.
