The National Botanical Garden of Iran, the largest such garden in the Middle East, was founded in 1968 in a suburb of Tehran.
The garden, which is 145 hectares in area, has a quite dry climate and an annual average rainfall of about 240 mm. It also serves as a botanical genetic bank for plants which are on the verge of extinction.
