异名

Filipendula vulgaris Moench f. ulmaria (L.) Maxim.

Filipendula ulmaria, commonly known as meadowsweet or mead wort, is a perennial herbaceous plant in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia (Near East and Middle East). It has been introduced and naturalised in North America.

Meadowsweet has also been referred to as queen of the meadow, pride of the meadow, meadow-wort, meadow queen, lady of the meadow, dollof, meadsweet, and bridewort.

Description

The stems, growing to 1–2 metres (3+1⁄2–6+1⁄2 ft) tall, erect and furrowed, reddish to sometimes purple. The leaves are dark-green on the upper side and whitish and downy underneath, much divided, interruptedly pinnate, having a few large serrate leaflets and small intermediate ones. Terminal leaflets are large, 4–8 cm long, and three- to five-lobed.

Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in irregularly-branched cymes, having a very strong, sweet smell redolent of antiseptic. They flower from early summer to early autumn and are visited by various types of insects, in particular Musca flies.

The flowers are small and numerous, they show 5 sepals and 5 petals with 7 to 20 stamens.

Names

The English common name meadowsweet dates from the 16th century. It did not originally mean 'sweet plant of the meadow', but a plant used for sweetening or flavouring mead. An earlier common name dating from the 15th century was 'meadsweet'.

Meadowsweet is known by many other names. In Chaucer's The Knight's Tale it is known as meadwort and was one of the ingredients in a drink called "save". It was also known as bridewort, because it was strewn in churches for festivals and weddings, and often made into bridal garlands. In Europe, it took its name "queen of the meadow" for the way it can dominate a low-lying, damp meadow.

The specific epithet ulmaria means "elmlike", possibly in reference to its individual leaves which resemble those of the elm (Ulmus). The generic name, Filipendula, comes from filum, meaning "thread" and pendulus, meaning "hanging".

Distribution and habitat

Meadowsweet is common throughout the British Isles in damp areas and is dominant in fens and wet woods.

Juncus subnodulosus-Cirsium palustre fen-meadow and purple moor grass and rush pastures BAP habitat plant associations of Western Europe consistently include this plant.

Diseases

Many insects and fungi cause disease in meadowsweet.

Meadowsweet leaves are commonly galled by the bright orange-rust fungus Triphragmium ulmariae, which creates swellings and distortions on the stalk and/or midrib.

The fungus Ramularia ulmariae causes purple blotches on the leaves.

The fungus Podosphaera filipendulae causes mildew on the leaves and flower heads, coating them with a white powder.

The midge Dasineura ulmaria causes pinkish-white galls on the leaves that can distort the leaf surface.

Uses

The whole herb possesses a pleasant taste and flavour, the green parts having a similar aromatic character to the flowers, hence the use of the plant as a strewing herb, strewn on floors to give the rooms a pleasant aroma, and its use to flavour vinegar, wine, and beer. The flowers can be added to stewed fruit and jams, giving them a subtle almond flavour. Some foragers also use the flowers to flavour desserts such as panna cotta. It has many medicinal properties. The whole plant is a traditional remedy for an acidic stomach. The dried flowers are used in potpourri. It is also a frequently used spice in Scandinavian varieties of mead.

Chemical constituents include salicin, flavone glycosides, essential oils, and tannins. In 1838, Raffaele Piria obtained salicylic acid from the buds of meadowsweet.

In culture

White-flowered meadowsweet has been found with the cremated remains of three people and at least one animal in a Bronze Age cairn at Fan Foel, Carmarthenshire. Similar finds have also been found inside a beaker from Ashgrove, Fife, and a vessel from North Mains, Strathallan. These could indicate mead or flavoured ale, or might suggest that the plant was placed on the grave as a scented flower.

In Welsh mythology, Gwydion and Math created a woman out of oak blossom, broom, and meadowsweet and named her Blodeuwedd ("flower face").

In the 16th century, when it was customary to strew floors with rushes and herbs (both to give warmth underfoot and to overcome smells and infections), it was a favorite of Elizabeth I of England. She desired it above all other herbs in her chambers.
