Filipendula
Filipendula is a genus of 12 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere. Well-known species include meadowsweet ("Filipendula ulmaria") and dropwort ("Filipendula vulgaris"), both native to Europe, and queen-of-the-forest ("Filipendula occidentalis") and queen-of-the-prairie ("Filipendula rubra"), native to North America. The species grow to between 0.5–2 m tall, with large inflorescences of small five-petalled flowers, creamy-white to pink-tinged in most species, dark pink in "F. rubra". "Filipendula" fruit are unusual, sometimes described as an indehiscent follicle, or as  an achene. "Filipendula" species are used as food plants by the larvae of some Lepidoptera species: emperor moth, grey pug, grizzled skipper, Hebrew character, lime-speck pug, mottled beauty and the satellite have all been recorded on meadowsweet. The species were in the past sometimes treated in a broad view of the genus "Spiraea", but genetic research has shown that they are less closely related than previously considered. The genus name "Filipendula" derives from the Latin words "thread" and "hanging", referring to the tubers of "F. vulgaris", which are attached to one other by thread-like roots.
