Blooming throughout the summer, this beautiful native perennial is a lightly scented, evening blooming prize. Missouri evening primrose is perfect as a ground cover or for the front of the bed, reaching only 6 to 10 inches in height. It features 4 to 5 inch yellow blooms that provide nectar for butterflies and moths. It prefers full sun in a limestone soil with good drainage but will tolerate light shade, poor soil and some drought. Under good conditions, it self-seeds. After the blooms are finished, then it sports winged seed pods.
