Nabalus albus is a tall, herbaceous plant with a robust, often purple-tinged stem that can reach up to 175 cm in height. The stems are typically erect, with a stout base and are often mottled or entirely purple. The leaves are large, ranging from ovate to triangular or cordate in shape, with sizes from 4 to 30 cm in length and 3 to 18 cm in width. The lower leaves have long, narrowly winged petioles and are usually glabrous on the upper surface, while the lower surface is pale, sometimes hirsute. The leaves are coarsely dentate or serrate, and in some cases, deeply 3-lobed. The plant produces 3-8 flower heads in dense, paniculiform clusters, with each head having a cylindrical to campanulate involucre. The phyllaries are lanceolate, purplish or maroon, and have scarious margins. The florets are white to pale pink, lavender, or red, with strap-shaped rays. The cypselae are elliptical to linear, and the pappi are typically reddish brown. The species is diploid with 2n = 32 chromosomes.

Nabalus albus is commonly found in a variety of habitats, including forests, woodlands, and anthropogenic (human-influenced) environments. It prefers moist to mesic soils and is often associated with disturbed areas such as roadsides and clearings. The plant is native to regions in Canada and the eastern United States, including provinces like Quebec and Ontario, and states such as New York, Pennsylvania, and Missouri.

Nabalus albus is not commonly cultivated but can be grown in garden settings that mimic its natural woodland habitat. It thrives in partial to full shade and requires well-drained, moist soil. The plant benefits from rich organic matter and consistent moisture. While it is not widely available in commercial nurseries, it can be propagated from seed or by division of its taproot. It is relatively hardy and can tolerate some shade, making it suitable for native plant gardens and naturalized areas.

Historically, Nabalus albus has been used in traditional medicine. The Iroquois applied a poultice made from the roots to treat rattlesnake bites, which is reflected in its common name, 'Rattlesnake-root.' The plant is also of interest to botanists and ecologists due to its ecological role in native habitats. While it is not widely used in modern horticulture, it can be a valuable addition to native plant gardens and restoration projects. Its showy flowers attract pollinators, making it beneficial for supporting local biodiversity.
