Silver Wings Evening Primrose. Narrow grayish leaves in a low branched rosette of leaves are perfect with the large 4" yellow flowers that open as the sun sets. Plant these where you can enjoy them during the evening wine stroll through the garden and then follow up with your morning coffee mosey. Good drainage, lean soil and sun. Well-suited for the rock garden, this Kansas and Nebraska native can take some dry.
