Every two years since the early 1970s, a magnificent flower carpet is created in the Brussels. This year it was the weekend of August 12. The predominant flower used in creating the carpet is the begonia. Apparently Belgium cultivates 60 million begonia tubers every year, and is recognized as the world's largest producer. Luscious colors and patterns in a beautiful setting of old European architecture!
