The Ongkharak District is well known for its ornamental plants and cut flowers. On Highway No. 305 (the Rangsit-Nakhon Nayok route), at Khlong 15, there are plenty of plant nurseries selling several kinds of plants ranging from miniature Bonsai plants to large species. Visitors to Thailand’s largest plant and flower center can purchase high-quality plants and flowers at reasonable or even wholesale prices. The market extends from Khlong 15 and down to Santi Dhamma Raj Bumrung Temple (approximately 4.5 kilometers). Alternatively, visitors are welcome to shop around at the Center, which is located nearby.
