History

Illustrated historical scene for Showy Japanese Lily

Lilium speciosum grows in subtropical woodlands of southern Japan, southeastern China, and Taiwan. German physician Philipp Franz von Siebold introduced it to Leiden Botanic Garden in 1832 from specimens collected during his service at the Dutch trading post Dejima in Nagasaki. Its waxy pink recurved flowers, powerful fragrance, and late summer bloom made it an immediate horticultural sensation across Europe.

Dutch breeders and later Oregon breeder Jan de Graaff used it as a principal parent for the Oriental hybrid group (Division 7) beginning in the 1940s—crosses with L. auratum and L. rubellum. Oriental hybrids now dominate the commercial lily trade with cultivars including 'Stargazer' (Leslie Woodriff, 1974), 'Casablanca', and 'Muscadet' grown by the millions worldwide.

The cultivar 'Rubrum' with deep crimson flowers and 'Uchida' became foundational parents in Oriental lily breeding, leading to the modern Oriental Hybrid class that includes 'Stargazer' (released 1975)—one of America's best-selling cut flowers of all time.
