The Botanical Garden Organization of Thailand was established on the recommendation of the Biodiversity Board of Thailand, to be responsible for the collection of various plants and vegetation, especially rare and endangered species of native flora, for further planting and propagation. The mission is to preserve the invaluable plant resources of the country. In 1992 Queen Sirikit celebrated her 60th birthday and the Botanical Garden Organization was established by Royal decree in honor of her Majesty. In 1994 Her Majesty the Queen granted her permission to name the northern botanical garden "Queen Sirikit Botanical Garden."

Headquarters building Established in the lush mountains of Doi Pui-Suthep on the Mae Rim-Samoeng road, these spectacular gardens could not be in a more splendid setting. Three major streams in the area converge into one, providing year round water, and the regional climate in this mountainous area is ideally suited to the project. In the early years, Queen Sirikit Botanical Garden was visited by directors and administrators from renowned botanical gardens around the world who unanimously gave their support to the project and over the years it has developed into a truly world class establishment. The center does not just provide botanical study and research facilities but also provides a place for relaxation where visitors are welcome to enjoy the beauty of Thai flora.
