Henry Eilers found this variant with finely quilled flower petals in a southern Illinois prairie remnant and was lucky enough to have this excellent plant named for him. True yellow flowers on tall stems in late summer with the ray florets gone totally tubular. Vanilla scented leaves are a plus.

Charming blooms of unusual gold quilled petals highlighted by chocolate-brown button centers. Good for cut flowers. A narrow upright grower which makes a great specimen in the back of the border. Very appealing in the late summer. Introduced by Larry Lowman of Ridgecrest Nursery.
