Silene chalcedonica (syn. Lychnis chalcedonica), the Maltese-cross, flower of Bristol, Jerusalem cross, or nonesuch, is a species of flowering plant in the family Caryophyllaceae, native to central and eastern Russia, Kazakhstan, Mongolia and northwestern China.
This plant was first formally named as Lychnis chalcedonica by Carl Linnaeus in 1753. For purposes of taxonomic stability, the genus name Lychnis was formally rejected in 1994 and the name Silene was conserved. The plant is now known as Silene chalcedonica, a name published by Ernst Hans Ludwig Krause in 1901.

It is a perennial herbaceous plant growing 35–100 cm (1.1–3.3 ft) tall with unbranched stems. The simple, broadly lanceolate leaves are produced in opposite pairs. Each leaf ranges between 2–12 cm (1–5 in) long and 1–5 cm (0.4–2.0 in) across.
The bright red flowers are produced in clusters of 10-50 together. Each flower 1–3 cm (0.4–1.2 in) in diameter with a deeply five-lobed corolla, each lobe being further split into two smaller lobes. This forms a general shape similar to that of the Maltese cross to which it owes one of its common names. The fruit is a dry capsule containing numerous seeds.
Cultivation and uses
It is a popular ornamental plant in gardens. It has gained the Royal Horticultural Society's Award of Garden Merit. Numerous cultivars have been selected, varying in flower colour from bright red to orange-red, pink or white. It grows best in partial to full sun and in any good well-drained soil, if provided with a constant moisture supply. The flowering period is extended if faded flowers are removed. It is short-lived in poorly drained soil. Double-flowered cultivars are propagated by division.
