European Meadowsweet Filipendula ulmaria

Meadowsweet is a large, flowering, herbaceous perennial that typically grows to 4 feet high. In the wild, it can be found on wet ground in swamps, marshes, wet woods and meadows, wet rock ledges and by rivers.  The plant is similar to Astilbe or Spirea, with tiny flowers in upright panicles. The flowers have a strong sweet smell that some people find objectionable. The leaves are also aromatic, though with a more pleasant scent. The genus name comes from the Latin words filum meaning a thread and pendulus meaning hanging and refers to the root tubers in some species that hang together with threads. The species name means resembling Ulmus the genus name of elms.

Meadowsweet does best in a humus-rich moist well-drained soil in semi-shade or in full sun if the soil is kept moist throughout the growing season. It does not tolerate dry or acid soils; however, it does grow well in heavy clay soils. If plants dry out, the leaves become scorched, but the plant can be cut back hard to generate new growth. The plant has a clumping habit and can easily be divided, allowed to root in a container, then replanted in the ground in the spring. It freely self-seeds and can spread out of control.

Diseases, Insect Pests, and Other Plant Problems: No known diseases or insect pests, although mildew can sometimes be a problem. Some Midwestern states consider this plant a noxious weed and do not allow it to be grown or transplanted where there is any danger of it spreading.
