Rhododendron is the city flower of Macheng and one of the top ten traditional famous flowers in China. Guifeng Mountain Rhododendron is renowned for its pure variety, vibrant colors, beautiful flower posture, and rich flower shapes, forming the most representative ecological landscape of the scenic area. Professor Guan Kaiyun, a famous authority in rhododendron research in China and professor of the Chinese Academy of Sciences, praised the Azalea Macheng with the "seven most": the most concentrated distribution, the purest forest structure, the largest population area, the oldest trees, the best preserved, the most beautiful plant type, and the most magnificent landscape, and praised it as a "world miracle", leaving a high praise of "Azalea Macheng is the best in the world". In 2010, Macheng successfully held the International Academic Symposium on Rhododendrons worldwide. More than 40 experts from around the world gathered at Guifeng Mountain and, after authoritative identification, confirmed that the ancient Rhododendron community in the area has a growth cycle of nearly a million years. Its scale and value have shocked the international academic community.
