Calystegia sepium R. Br.
Snårvindan climb fences, hedges and other support that can provide attachment to its long, thin stalks with large, white trumpet-shaped flowers. Snårvindan has no tendrils, but is a typical vine
that winds itself around other plants, among other specimens of the same species by growth movements. The Swedish name of the plant - as well as the scientific species name sepium, of the Latin word suepes, hedge - alluding to its common habitats. There are several cultivated forms of thicket reel, but the wild form is extremely decorative, without prejudice to the considered weeds and therefore unwelcome in most gardens.
Snårvindan seems early to have been appreciated because of roots and leaves sharply removal effect. During the Middle Ages thicket reel of the Arab doctors as a means of jaundice.
Although the closely related åkervindan, Convolvulus arvensis, which is considerably smaller and smaller, bright red flowers, is useful as a laxative, it is less active than snårvindan. Åkervindan also act as a very troublesome weed.
