Plant Profile: Rudbeckia laciniata

The Green-Head Coneflower is a robust herbaceous perennial that typically reaches heights of 3 to 10 feet, exhibiting a tall and slender form, though it may only grow to about half that size when cultivated. This plant thrives in moist environments but adapts well to average, well-drained soils, flourishing in full sun to partial shade. It is commonly found in various habitats, including woodlands, meadows, streambanks, and roadside ditches. While it can withstand hot and humid summers, it has a tendency to spread vigorously through underground rhizomes.

To manage its growth, it is advisable to divide clumps and remove spent flowers to promote further blooming. The Green-Head Coneflower produces striking yellow flowers measuring 2 to 4 inches across, which bloom from late summer into fall. Its foliage features lower leaves that are divided into one or two pairs of toothed lobes, while the upper leaves may be lobed or unlobed. A rosette of leaves at the base of the stem remains through winter, providing an appealing ground cover during the colder months.

This plant attracts butterflies seeking nectar from its flowers, and in the fall, songbirds, particularly American Goldfinches, feed on its seeds. It is also moderately resistant to deer.

Ideal for meadows and open spaces, the Green-Head Coneflower was honored as the 1995 NC Wildflower of the Year, a recognition facilitated by the North Carolina Botanical Garden with support from the Garden Club of North Carolina.

In terms of pests and diseases, the plant does not face significant issues, although taller specimens may require some support, and it can become weedy in certain conditions.
