Pak Klong Talat is the country’s biggest flower market and has a long history. During the reign of Rama I (1782–1809), a floating market took place on the site of the modern Pak Khlong Talat; by the reign of Rama V (1868–1910), it had changed to a fish market. The fish market was eventually converted to today's produce market, which has existed for over 60 years. The market's focus has shifted from produce to flowers as the Talat Thai market on the outskirts of Bangkok has become a more attractive site for produce wholesaling.
Though the market is open 24 hours, it is busiest before dawn, when boats and trucks arrive with flowers from nearby provinces, and after dusk, when wholesalers from the provinces set up their colourful booths. The footpaths on both sides of Maha Rat Road from the foot of Memorial Bridge to Klong Lod are packed with flowers of all kinds and colours. Amidst the hustle and bustle you can find a tremendous variety of orchids, lotus, jasmine, roses, and the more expensive lilies and carnations. All flowers and many decorative items are available at very low prices, for example, a bunch of 50 roses will only set you back Bht 40.
