Lychnis chalcedonica L.
Scarlet lychnis, burning love, dusky salmon, flower of Bristol, Jerusalem cross, Maltese cross, nonesuch
Scarlet lychnis is native to central and eastern Russia, Kazakhstan, Mongolia and northwestern China. They are popular as garden plants in North America, and often escape cultivation.
Identification: Plants are 14-39" (35-100 cm) in height, rarely branching, with hairy stems. Leaves are opposite, ovate to broadly lanceolate, ¾-4½" (2-12 cm) × ⅜-1¾" (1-5 cm). Flowers are in dense umbels of 10-50, blooming June to August, depending upon climate. Each flower is brilliant red or red-orange, ½-¾" (1.5-2 cm) across, split into five heart-shaped lobes, each of which is again split into a Y-shape, forming a sort of pentagonal Maltese cross.
