Salahesh Fulbari (Nepali: सलहेश फुलवारी), also known as Fulbari Mela, is a garden of historical and cultural significance to the south of East West Highway in Lahan Municipality, Siraha District, Province No. 2, Nepal. It is famous for an orchid that is believed to bloom only on the eve and first day of year, Baishakh, the first month of the Bikram Sambat calendar. This funfair is held at 4 km West from the city of Lahan at the area of 14 Acres.

Named after local demigod Salahesh, the garden receives thousands of pilgrims from different parts of Nepal and India each year on the first day of Baishakh. The orchid grown at the tree is taken as a token of love between Salahesh, who is often taken as a folk hero in the Mithila region, and his beloved Malini. A temple has made with the statues of them at the side of the tree. The garden only opens on the New Year’s Eve. It is said that all the other days except than New Year day, the garden is filled with wild animals magically. Hence, no one is allowed to get into the premises on other days. According to priest, unlike other flowers, the leaves of this flower never fall on the ground, adding to the flower’s intrigue.

Later, he himself was declared as King of Maisotha state by Motiram, son of King Kulheswor. Maisotha is the birthplace of Salahesh which lies near the Siraha district headquarter. Salahesh belongs to the Dusadh community.
