Tree introduction: The roads in Dali Butterfly Spring Park are lined with newly planted trees such as bamboos and Christmas trees to welcome guests. Behind the spring, there are pine forests, cypress trees, palm forests, tea forests, and rhododendron forests all over the mountains and plains. , Moso Bamboo Forest, and Butterfly Spring are home to Dali's unique aromatic tree species such as Albizia Julibrissin, Sour Fragrance Tree, and Pistacia chinensis. Among them, the largest Albizia Julibrissin tree blooms in early April, and its petals open like butterflies during the day. At night, the petals close up and spit out bursts of fragrant fragrance, which is vividly praised by the poet as a "still butterfly". During the Butterfly Festival, flowers and butterflies dance together, and it is difficult to distinguish between true and false. It is a great spectacle in Dali Butterfly Spring.
