Yellow Loosestrife Lysimachia punctata

Phonetic Spelling
lis-ih-MAK-ee-ah punk-TAY-tah
Description

Dotted loosestrife is an herbaceous, perennial flower in the Primulaceae (primrose) family.  It is native to Asia and southern/central Europe.   It was introduced into North America for ornamental gardens but has naturalized widely in the U.S. and Canada in damp, sunny areas such as ditches, meadows, roadsides and stream banks. It is a tall, erect, rhizomatous plant reaching 3 feet in height, forming large mounding colonies with attractive whorled leaves.  A spike of yellow flowers with an orange-red center blooms from late spring to fall.  It is best utilized as a naturalized groundcover in wild gardens or remote beds or borders where aggressive, unwanted spread into lawns or other perennial beds is not a concern. It primarily spreads through rhizomes but may also self-seed.  This plant prefers rich, moist, well-drained soils in full sun to part shade. Growth is less aggressive in dry, shady soils.

The species name means spotted.
