Lysimachia terrestris has been introduced in cranberry bogs and is occasionally found on muddy lake shores of the Pacific Northwest (British Columbia, Oregon, Washington).

A fairly widespread hybrid between Lysimachia terrestris and L. thyrsiflora has been widely reported and named L. ×commixta Fernald. The parents may or may not be found in the vicinity of hybrid populations, which can form extensive colonies through vegetative reproduction of rhizomes or bulblets. J. D. Ray (1956) indicated that the hybrids are “relatively infertile,” with abnormal pollen grains.
