The Udon Sunshine Orchid Farm, just northwest of town, earned fame for developing an aromatic breed of orchid and producing the first orchid-based perfume. It has since developed a hybrid of Codariocalyx motorius ohashi leguminosae, a succulent that 'dances' to music. If you sing or talk to the plant in a high-pitched voice, a few smaller leaves will shift back and forth. The plants are most active from November to February and from 7am to 9.30am and 4.30pm to 6.30pm.
You can buy Udon Dancing Tea (now very popular for its supposed medical benefits; each batch sells out quickly), made from the plant, along with the Miss Udon Sunshine orchids and perfumes.
To get here, go to the 'Welcome to Nongsamrong Community' sign on Rte 2024, then after 150m follow the 'Udorn Sunshine Fragrant Orchid' sign. Sŏrng·tăa·ou 6 and the 'yellow bus' get you close to it. A túk-túk from Udon's city centre should cost 60B to 70B.
