Packera obovata

Roundleaf ragwort

A more upland species versus P. aurea
More withstanding of sun and heat
Bloom time overlaps with, but starts a tad later P. aurea
Basal leaves differentiate the two species - P. obovata is more oval shaped whereas P. aurea has a more round, heart-shaped appearance
Foliage forms a 4-6ā€ tall mat; flower stalks reach 10-16ā€ tall

A tough groundcover, Packera obovata is similar to its popular cousin, Packera aurea, but with a smaller round leaf and the ability to withstand drier, full-sun conditions without losing its verdant appearance!

Roundleaf ragwort Interesting Notes

Packera obovata, commonly called roundleaf ragwort, roundleaf groundsel or squaw weed, is valued for its ability to thrive in shady locations, naturalize rapidly and produce a long and profuse spring bloom of bright yellow flowers. It is native to rocky wooded hillsides, open rocky glades, limestone ledges, stream banks and moist meadows from Quebec and Ontario south to Texas and Florida. In Missouri it most often is found in the Ozark region in the southern and central part of the State (Steyermark). Flat-topped clusters (corymbs) of daisy-like flowers (3/4" diameter) with yellow rays and yellow central disks bloom in spring (April-June) atop sparsely-leaved stems rising to 18" tall. Flowering stems rise from a basal clump of serrate, rounded to spatulate leaves (to 2-4" long) each of which tapers at the base into a long petiole. Upper stem leaves are much smaller, sessile and pinnately lobed. Foliage is semi-evergreen in St. Louis. This plant was originally designated as Senecio obovatus. -Missouri Botanical Garden


The huge genus Senecio, a member of the daisy family. Its name is rooted in the Latin senex, for "old man", though the genus is neither stooped, frail, crochety, nor inherently wise. The story's much more homespun than that. Turns out that once upon a time, a botanist gazed upon the plant's fluffy, white seed heads and was reminded of his own grandfather's head of wiry, silver-gray hair. The suggestion was so strong, the botanist borrowed the image to give the plant its Latin name.


Charming, no? So what if I made it up, the explanation's entirely plausible. What is true is that the "old man" reference has been knocking around since the first century A.D., when the great naturalist Pliny made note of the plant's hoary, senescent flowers. - Ketzel Levine's Talking Plants

Packera obovata Growing and Maintenance Tips

Easily grown in average, moist, well-drained to dry-mesic soil conditions in full sun to part shade. Blooms well in shady locations. Tolerates some soil dryness. Naturalizes into large colonies in optimum growing conditions by both self-seeding and stolons. Remove flowering stems after bloom and/or dispersal of seed. Basal foliage will serve as an attractive ground cover (to 4-6" tall) throughout the growing season.
