Fragrant Evening Primrose: Silken white blossoms unfurl each evening over shiny deep green mounds of leaves, slipping to a rosy tint with midday heat. The fragrance is sweet and exotic, contrasting sharply with the native surroundings of dry foothills, shrub steppe and pinyon-juniper. Tolerant of poor well-drained soils, and clay. Firewise.
