Tianwei Highway Garden is a massive horticultural corridor in Changhua County, Taiwan, functioning as the nation's primary hub for flower and plant cultivation. The area spans over 400 hectares, hosting hundreds of individual commercial nurseries and private gardens along a scenic route. It is distinct for its widespread use of high-intensity incandescent lighting at night, specifically utilized by local chrysanthemum growers to manipulate blooming cycles. Visitors navigate the extensive garden trails primarily by renting bicycles or electric quadricycles from numerous local vendors. The route is dotted with diverse landscaping styles, ranging from traditional bonsai displays to European-style manicured gardens and tropical succulents. Unlike a single enclosed botanical park, it is a sprawling, open-air agricultural district where production and tourism coexist. The landscape changes seasonally based on the flower crop cycles, including hydrangeas, lilies, and petunias.
