Yellow coneflower (Ratibida pinnata) Perennial. It grows from Ontario Canada down to Georgia and of course, all the prairie states. It grows to about 3' tall, sometimes 4' so would be best at the back of the border. Butterflies and bees like this plant. Quite drought tolerant, it prefers full sun, and water occasionally. Blooms from July to September and it transplants easily. Pretty companion bloomer to the monardas. Will spread by seed, but not rampantly.
