Yellow Loosestrife - Lysimachia vulgaris

    Description

    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).
