Lysimachia clethroides is
a perennial herb inhabiting sunny grasslands in hills, growing to
0.6-1m in height and propagating by rhizomes extending long. Stems
wear sparse short hairs with somewhat red bases. The leaves are of
alternate phyllotaxis with sharp tips, 6-13cm in length, long-oblong
or oblong-ovate. Stem tips give birth to 10-30cm long racemes,
setting many white flowers. Corollas measure approximately 1cm in
diameter and are deeply cut into five. Bloom time: June-July.
