Experts believe that the production focus has moved from traditional growers to countries where the climates are better and production and labor costs are lower. This has resulted in a paradigm shift in the floral industry. The Netherlands, for instance, has already shifted attention from flower production to flower trading, though it plays an important role still in the development of floricultural genetics. The new centers of production are typically Third World countries like Colombia (second largest exporter in the world), Ecuador, Ethiopia, Kenya, and India. Other players in this global industry are Israel, South Africa, Australia, Thailand and Malaysia. New Zealand, due to its position in the Southern Hemisphere, is a common source for seasonal flowers that are typically unavailable in Europe and North America.
In Africa, Kenya is the largest exporter, suppling a large percentage of Europe's flowers, the industry there is represented by the Kenya Flower Council.
In South America, Colombia is the leading flower producer and exporter accounting for 59% of all flowers imported to The United States in 2006. The United States imports 79% of its flowers. Ecuador has become, in recent years, the leading South American rose producer and is well known throughout the world for its high quality, large headed roses due to the high altitude location of its rose farms.
