Packera paupercula is a flowering plant species of the genus Packera and family Asteraceae, native to North America, where it is widespread across Canada and much of the United States.[1] Its common names include balsam ragwort and balsam groundsel.[2]

It is taxonomically complex, and many have proposed, or expect future proposals, to break it into species, subspecies, varieties, forms, and races. However, no such classification to date has received wide acceptance.[1][3] It flowers as early as April in the southern part of its range, and as late as August in the northern part of its range.[1][3]
