The tall stalks support bright, yellow single lush flowers with umbrella-like leaves that surround huge centers that are filled literally with up to one thousand with seeds. Sometimes the heads get so large that the stalk begins to bend but quite often they grow up straight and tall. Seeds are very attractive to birds.
