Rudbeckia maxima (Large Coneflower)


Clump-forming perennial that produces large golden yellow flowers with distinctive elongated pollen cones from mid summer to early fall.  Plants form a base clump of bluish green leaves from which rise the flower stalks, sometimes up to 7' tall.  Clumps have a spread of 3'-4' and often naturalize by self-seeding.  Prefers full sun exposure in moist, rich soil but will tolerate a variety of soil conditions including clay.  Pollinator friendly; seed heads are attractive to birds.
