Lysimachia ciliata L.
Fringed Loosestrife, Fringed Yellow Loosestrife
Primulaceae (Primrose Family)
Synonym(s): Steironema ciliatum, Steironema pumilum
USDA Symbol: LYCI
Fringed Yellow Loosestrife is an erect to sprawling, often branched perennial, usually 1-2 ft. tall, forming large masses of pale-green, lance-shaped foliage. An erect stem, unbranched or branched, bearing five-petaled yellow flowers rising on stalks in axils of opposite leaves; leafstalks fringed with spreading hairs.
The name emphasizes the hairy leafstalks of this wetland plant, which is sometimes placed in the genus Steironema. Southern Loosestrife (L. tonsa) has smooth leafstalks, grows only to 3' (90 cm) tall, and occurs from Kentucky and Virginia south to Georgia and west to Texas. Lance-leaved Loosestrife (L. lanceolata) has narrow leaves tapering to the base and occurs in a range similar to that of Fringed Loosestrife but not in Canada or the northern Plains states. Trailing Loosestrife (L. radicans) has very weak stems, virtually trailing on the ground, and occurs in the south-central United States east to Florida and Virginia.
