Description: Herbaceous, hermaphrodite, perennial plant of 50-150 cm height with an upright habit.
Narrowly oval, pointed leaves grow in clusters of three or in opposite pairs and are almost stalk less.
The flowers are golden-yellow with red spots at the base, in terminal or axillary panicled cymes, which are simple or compound. The corolla is more or less bell-shaped, the 5 lobes entire, egg-shaped, not fringed with hairs, without alternating teeth. The lobes of the calyx are lance-shaped, fringed with hairs, with red margins. The 5 anther-stalks are united below, and the stamens included. The capsule is round. The seeds are rough with a border, 3-angled.
Biology: The flowers no bloom from July to September. It is a perennial, propagated by-division, and is worth cultivating. Flowers are visited by pollen-seeking insects. An insect that is especially abundant where these plants are found is Macropis labiata; where it does not occur the plants are absent.
Habitat: Wetlands, damp meadows and forests.
Uses: An astringent herb, yellow loosestrife is principally used to treat gastrointestinal conditions such as diarrhea and dysentery, to stop internal and external bleeding, and to cleanse wounds. Yellow loosestrife makes a serviceable mouthwash for sore gums and canker sores, and may be used to treat nosebleeds. Yellow loosestrife has also been taken as an expectorant.
