Rudbeckia subtomentosa 'Henry Eilers'
('Henry Eilers' sweet coneflower)
The unique, finely quilled, 2-inch-wide flowers are what make 'Henry Eilers' stand out from the rest of the coneflowers. The petals sit separate from one another, forming a brilliant, golden yellow starburst around a dark brownish purple cone. The blooms grow on strong, upright, 4- to 5-foot-tall stems in late summer, and are produced in such abundance that you can cut some for bouquets and you'll never even notice they are missing from the garden. The stems are covered with a soft, hairy down, while the leaves have a pleasing vanilla-and-anise scent.
