Yellow Loosestrife - Lysimachia vulgaris
A tall, (to 1.5 m high) herb with an unbranched stem except for branches of the terminal inflorescence. The leaves, except for the very lowest, are in whorls of 3 to 4. These leaves are narrowly ovate, without distinct teeth, but with a slightly wavy margin. The petioles are short and some leaves may appear sessile. The flowers are about 1.5 cm across and bright yellow. Their stalks (pedicels) are 1 cm or less, which distinguishes them from L. ciliata, which has longer flower stalks (2 to 4 cm).
Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed.
Lysimachia vulgaris is a marginal plant and thrives in wet peaty soil beside rivers, lakes and in other marshy places.
In flower during July, August and September.
A semi-evergreen perennial spreading vegetatively by very long thin rhizomes to form large colonies in permanently wet places.
A rather localised distribution in Britain with most records coming from the north and west plus East Anglia.
Rare as a native in Leicestershire and Rutland although cultivated plants may escape and confuse the distribution picture.
