About
Lysimachia vulgaris, the yellow loosestrife or garden loosestrife, is a species of herbaceous perennial flowering plant in the family Primulaceae. It was transferred to Myrsinoideae based on results of molecular phylogenetic research before being merged into the Primulaceae.
Where it grows
L. vulgaris is native to Eurasia, as far West as Ireland where it is frequent to locally common, and North Africa. It has been introduced to North America, where it is considered an exotic introduction, for its ornamental value in gardens. It grows best in moist habitats such as fens and wet woodlands as well as on lakesides and riverbanks.
