Filipendula rubra, also known as queen-of-the-prairie, is a species of flowering plant in the family Rosaceae native to the northeastern and central United States and southeastern Canada.

[9] The typical habitat of F. rubra is wetland plant communities, particularly calcareous fens, although it is occasionally found in spring seeps and wet prairies.

With large lobed leaves and branching red stems, it produces corymbs of deep pink or peach, sweet fragrant flowers in the summer.

Native Americans have used the root of F. rubra in traditional medicine for treating heart problems and as an aphrodisiac.

[16] The root has a high tannin content, making it useful as an astringent for treating diarrhea, dysentery, and bleeding.

A good number of both native and conventional nurseries sell some, yet it is still an uncommon plant in most American gardens and landscapes.

It grows in full sun or part-shade and needs moist to draining wet soil; it suffers from drought.

Although aesthetically appealing for humans, F. rubra, based on current knowledge of the plant's floral and faunal associations, offers comparatively little value to wildlife.

It competes for continually shrinking, due to human development, wetland acreage with plants that support more wildlife.

As a result, some conservationists suggest using this plant in aesthetics-oriented gardens but focusing more on other species for restoration work.
