FAMILY NAME COMMON
FAMILY SCIENTIFIC NAME
Lysimachia vulgaris is an herbaceous perennial with erect stems up to 1 m (3.3 ft.) in height and long, stolon-like rhizomes that can run 10 m (33 ft.) long. The leaves of this plant are opposite or whorled. They have small glands that are black or orange in color and soft hairs beneath. They are lanceolate to laceolate-ovate in shape, 7-12 cm (2.75-4.75 in.) in length and 1.5-4 cm (0.6-1.5 in.) in width. The middle and upper leaves have short petioles and are acuminate. The inflorescence is a terminal, leafy panicle that appears June-September. The flowers are have five yellow petals and are 1.2-2 cm (0.5-0.75 in.) across. The lobes of the calyx are red-margined and 3.5-5 mm (0.15-0.2 in.) long. The fruits are dry capsules.

Lysimachia punctata L. (spotted loosestrife) The main differences between Lysimachia vulgaris and L. punctata is that the calyx of L. punctata lacks the red margin, and its inflorescence tends to be denser.
The seeds of this plant are most likely water-dispersed. However, the main method of dispersal for this plant is via rhizomes.
Lysimachia vulgaris is native to Europe. It has become naturalized in the northeastern part of Canada. In the United States it has been reported from all northeastern states, west to Minnesota and Illinois and south to Kentucky. There have also been reports from Washington, Oregon, Montana and Colorado. It has been reported from all New England states.
HISTORY OF INTRODUCTION IN NEW ENGLAND
This plant was most likely brought over by settlers from Europe for use in gardens. The earliest records in New England are from the early 1900's.
HABITATS IN NEW ENGLAND
Edge, Herbaceous Wetland, Lake or Pond, Open Disturbed Area, River or Stream, Roadside, Salt Marsh, Wet Meadow, Yard or Garden. Lysimachia vulgaris prefers moist soil, and will invade fens, wet woods, lake shores, rocky river shores and riparian zones.
Lysimachia vulgaris presents a similar threat as the serious invasive Lythrum salicaria (purple loosestrife). In Washington state it has been reported as possibly outcompeting Lythrum salicaria in wetland habitats. The rhizomes spread readily. Though its populations have not yet reached the numbers of Lythrum salicaria populations, it has the potential to do so.
Documentation required: Herbarium specimen or mounted snippet of the inflorescence. Best time for documentation: Summer.
