Filipendula ulmaria
Filipendula vulgaris
Filipendula ulmaria is cultivated as an ornamental and sometimes escapes. The species is fairly common and relatively persistent or locally spreading from old gardens and thoroughly established well into the wild at some locations in the Maritimes. The native range stretches from Atlantic Europe to eastern Siberia (basin of Lena River), and from the Arctic Circle to the Altai Mountains of southern Siberia.
Two or three varieties or subspecies are often recognized within Europe and Russia in Filipendula ulmaria in the broad sense. Among them, subsp. picbaueri (Podpěra) Smejkal represents a separate species, F. stepposa Juzepczuk, and does not occur in North America. Two other frequently used infraspecific names are subsp. denudata and subsp. ulmaria, the former sometimes also regarded as a separate species. The latter has abaxially grayish tomentose leaves; the former has leaves only minutely hairy along the nerves. The full spectrum of intermediates usually occurs within a single population, and both forms clearly belong to the same species (I. A. Schanzer 1994). Both of them may occur in North America as escapes from cultivation.
The flowers contain tannins and salicylates and are thought to reduce pain and fever, mildly. They have also been used to treat stomach complaints, such as heartburn. Some research in laboratory animals has been conducted to investigate their effectiveness for ulcers, but results are not conclusive. Some laboratory studies appear to show that the flowers and seeds contain a chemical similar to heparin. That and the salicylate component may have some inhibiting effect on blood clotting (O. D. Barnaulov and P. P. Denisenko 1980; S. Foster and J. A. Duke 1990; B. A. Kudriashov et al. 1990, 1991). None of these properties have been documented by well-controlled clinical studies.

Filipendula vulgaris has been cultivated as an ornamental in North America and probably escapes. The native range stretches from Atlantic Europe to southwestern Siberia (Altai Mountains), and from southern Scandinavia to northern Africa. Despite strong morphologic differences from the other species of Filipendula, it is probably related to F. ulmaria (I. A. Schanzer 1994). Two additional names have been associated with this species: Filipendula hexapetala Gilibert is a rejected name, and F. hexapetala Gilibert ex Maximowicz is illegitimate.
