Built in 1931, the Montreal Botanical Garden is dominated by the French garden style. It is divided into greenhouses and outdoor parks with various themes. It is planted with tens of thousands of plants and is the largest botanical garden in North America. In 1984, Mr. Wu Yisun donated his collection of bonsai, and now the bonsai area of the Botanical Garden has become a larger bonsai exhibition area outside of Asia. The tropical rainforest is a greenhouse that displays lush rainforests such as climbing creatures and epiphytic organisms. Greenhouses in arid regions show plants such as aloe tequila in the African desert.
