Rudbeckia laciniata

Along the wooded riverbank, a yellow wildflower rises above the nettles, and with its petals bowed gently towards the silty earth, looks out across the flowing stream. Judging by its stature and bloom, the enchanting cutleaf coneflower seems to have strayed from the meadow, but indeed it is at home in the partial shade of the riparian woodland. As such, it makes a rare contribution to the ecosystem aesthetic, both in the natural landscape and in the home garden. For those desiring a tall, showy wildflower, but constrained by a garden space with suboptimal lighting, cutleaf coneflower is a great choice. Additional attractions include exquisite, deeply lobed leaves, and the bustling pollinator community that the plant seems to bring with it.

Distinguished by the Xerces Society for possessing special value to native bees, cutleaf coneflower also attracts moths, skippers, butterflies, wasps, and flies. Similar to other Rudbeckia species, black-eyed Susan and brown-eyed Susan, cutleaf coneflower’s floral rays display ultraviolet coloration invisible to the human eye, but visible to bees. To a bee, the rays encircling the plant’s flowerhead are two-toned, like a bullseye indicating the presence of floral rewards. To judge from all the buzzing around the flowerheads, the bees are pretty good at hitting the mark!

Cutleaf coneflower produces its attractive blooms near the tops of its 6-8’ stems for approximately one month in late summer. Native to NE Ohio habitats including riparian woodlands, swamps, and the margins of wet woods, cutleaf coneflower grows well in conditions of full to partial sun and wet to average soil. Spreading by means of underground stems, the plant can become aggressive in some situations. Common associates of cutleaf coneflower in partially shaded zones include wingstem, late figwort, foxglove penstemon, and oxeye sunflower.
