Packera obovata, more commonly known as roundleaf ragwort, is a herbaceous perennial native to eastern North America, ranging from Quebec and Ontario south to Florida and west to Kansas and eastern Texas, and occurring widely across Pennsylvania.

From May to early July, a profusion of yellow, daisy‑like flower heads appears atop sparsely‑leaved stems, each ¾‑inch bloom carrying many bright ray florets around a central mound of yellow to orange‑yellow disk florets. The dull green to purple‑green stems rise up to 18 inches from a broad basal rosette of spatulate, 2–4 inch leaves with toothed margins. Above the rosette, sessile, alternate stem leaves become progressively smaller and are typically deeply lobed or pinnately cut.

This species favors rocky glades, limestone ledges, stream banks, and wooded hillsides, thriving in partial shade and moist, humus‑rich soil. Its short rhizomes and creeping above‑ground stolons allow it to form steady, weed‑suppressing colonies across the forest floor. After flowering, Packera obovata forms small brown achenes topped with soft white tuft of silky bristles, creating delicate dandelion‑like seed heads that drift on spring winds and provide food for the white‑crossed seed bug.

Roundleaf ragwort provides early nectar for a wide variety of native bees, small butterflies, and spring pollinators. Like other Packera species, its foliage contains pyrrolizidine alkaloids, making it strongly deer and rabbit resistant.
