This is one of my favorite rudbeckias. Similar overall to R. hirta, but individual flowers are smaller and produced in much larger numbers, and it is much more perennial. Three feet tall at least, and covered with bloom for the second half of the summer. Vigorous, easy, and well worth growing. Zone 4
