Rudbeckia subtomentosa has 3″ yellow flowers with dark brownish-purple, shiny center disks on branched stems. The flowers faintly smell of anise, hence the common name of sweet coneflower. Leaves have a soft fuzzy texture. Deadhead spent flowers to encourage additional bloom. Special value to native bees.
‘Henry Eilers’ has 2″ true yellow flowers, rolled lengthwise into a quill shape. Other than the difference in petal shape, this plant closely resembles the straight species.
