November : The hillsides of Khun Yuam and Mae Sariang districts are filled with a host of golden Bua Tong Blooms. As gay as a daisy and almost as large as a sunflower, the Bua Tong only blossoms for a month.
At Doi Mae U-Kho, the blossoms appear profusely. Finally, the golden blooms become part of the scene. Some specialists have classified these Bua Tong as weeds and because of this, they may be cleared to make way for cash crops. Fortunately a group of researchers have discovered the flower's insect-repellent properties. And perhaps that is why the Bua Tong, a symbol of Mae Hong Son, is still preserved on the hillsides.
