There are three categories of floral emblem that symbolise Indonesia:
National flower of Indonesia is Melati putih
Flower of charm is Anggrek Bulan )
Rare flower is Padma Raksasa Rafflesia. All three were chosen on World Environment Day in 1990. On the other occasion Bunga Bangkai was also added as puspa langka together with Rafflesia.
Melati putih, 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 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. Melati putih is also the most important flower in wedding ceremonies for ethnic Indonesians, especially in the island of Java. Jasmine flower buds that haven't fully opened are usually picked to create strings of jasmine garlands called roncen melati. On wedding days, a traditional Javanese or Sundanese bride's hair is adorned with strings of jasmine garlands arranged as a hairnet to cover the konde. The intricately intertwined strings of jasmine garlands are left to hang loose from the bride's head. The groom's kris is also adorned with five jasmine garlands called roncen usus-usus to refer its intestine-like form and also linked to the legend of Arya Penangsang. In Makassar and Bugis brides, the hair is also adorned with buds of jasmine that resemble pearls. Jasmine is also used as floral offerings for spirits and deities especially among BalineseHindu, and also often present during funerals. The jasmine has wide spectrums in Indonesian traditions; it is the flower of life, beauty and festive wedding, yet it is also often associated with spirit and death. In Indonesian patriotic songs and poems, the fallen melati often hailed as the representation of fallen heroes that sacrificed their life for the country. The Ismail Marzuki's patriotic song"Melati di Tapal Batas" and Guruh Sukarnoputra's "Melati Suci" clearly refer jasmine as the representation of fallen heroes, the eternally fragrance flower that adorned Ibu Pertiwi. The other two national flowers were chosen for different reasons. Moon Orchid was chosen for its beauty, while the other two rare flowers, Rafflesia arnoldii and Titan arum were chosen to demonstrate uniqueness and Indonesian floral biodiversity.
Each of 34 Provinces of Indonesia also have native plants used as floral emblems. This is a list of Indonesian floral emblems, which represent the provinces of Indonesia.
