Jasminum sambac
"Melati putih" ("jasminum sambac"), a small white flower with sweet fragrance, has long been considered as a sacred flower in Indonesian tradition, as it symbolises purity, sacredness, graceful simplicity and sincerity. Although the official adoption were announced only as early as 1990 during World Environment Day and enforced by law through Presidential Decree ("Keputusan Presiden") No. 4 1993, the importance of "Jasminum sambac" in Indonesian culture predates its official adoption. Since the formation of Indonesian republic during the reign of Sukarno, "melati putih" is always unofficially recognised as the national flower of Indonesia. The reverence and the elevated status of this flower mostly due to the importance of "jasminum sambac" in Indonesian tradition since ancient times.
