Rudbeckia subtomentosa 'Henry Eilers' (Sweet Coneflower)

Rudbeckia subtomentosa 'Henry Eilers', is a cultivar of sweet coneflower, a medium-to-large sunflower-like perennial wildflower, closely related to black-eyed Susans. As a relatively large wildflower, Rudbeckia subtomentosa has narrow, branching stems that typically grow to about 3-5' tall in 1-2' wide clumps. Rudbeckia subtomentosa is typically found in open woodland environments or along creeks and other low-lying areas much of the central United States, and while this makes them an irregular choice for gardens of the northeast, their ornamental and ecological appeal is not to be missed. Originally found as a chance mutation in a railroad prairie area in Montgomery County, Illinois by its namesake discoverer Henry Eilers, the flower is set apart from other coneflowers and black-eyed Susans by its golden-yellow rolled petals, which form a tube shape instead of a typical flat ray, adding an incredibly unique look to any garden. 'Henry Eilers' can bloom from mid summer all the way through to the fall, and with its fragrant leaves, it make an excellent addition to beds and in cut flower arrangements.

Moderately deer-resistant and beneficial for pollinators and birds, 'Henry Eilers' sweet coneflower tolerates a wide range of environments, including a range of soil types and weather conditions. Due to its native habitats being relatively hot and wet, Rudbeckia subtomentosa prefers medium-moist soils and full sun, but can tolerate drought conditions, clay soils, and super hot and humid summers. While 'Henry Eilers' can be used in home landscapes, such as rain or pollinator gardens, Rudbeckia subtomentosa is also an excellent choice for naturalized meadows and open areas thanks to its hardiness and attractiveness to pollinators, including a number of butterflies.
