Lysimachia terrestris

Lysimachia terrestris (L.) Britton, Sterns & Poggenb.

Earth Loosestrife, Swamp Candles

Primulaceae (Primrose Family)

Synonym(s): Lysimachia terrestris var. ovata

USDA Symbol: LYTE2

USDA Native Status: L48 (N), CAN (N), SPM (N)

Erect stems with opposite leaves and racemes of star-like, yellow flowers with 2 red spots at the base of each petal.

This handsome species was introduced into Cranberry bogs in the Northwest from the East. In a wetland garden this showy species will spread rapidly by underground stems. Loomis Loosestrife (L. loomisii), with candle-like clusters of yellow flowers and whorled, very narrow, 1-inch-long (2.5 cm) leaves, occurs from North Carolina to Georgia. Tufted Loosestrife (L. thyrsiflora), looks very different, with flower clusters borne from the axils of the lower leaves. It is found in swamps and bogs in much of Canada, south to New Jersey, west to West Virginia, Missouri, Colorado, and California. Swamp Candles freely hybridize with Whorled Loosestrife (L. quadrifolia), producing lovely intermediates, and with Tufted Loosestrife, producing plants with both terminal and axillary flower clusters.
