This drought tolerant perennial establishes readily from Primrose seeds, and once you have smelled its sweet almond fragrance, you will want this flower in your xeriscape garden! The White Buttercup flower fades to pale pink and is cup-shaped and delicate. The Pale Evening Primrose is vigorous plant and begins blooming just two months after starting the flower seeds which is very unusual for a perennial.
