The carpet exists for one weekend only, in mid-August in the Market Square of Brussels, the capital of Belgium. It consists mostly of begonia plants placed directly on cobblestones (and presumably watered heavily every evening). Begonias are from the West Indies, but have been cultivated around Ghent area since 1860. The carpet is edged with turf and the flowers are packed together, 300 per square metre. The carpet uses about 700,000 flowers. After the pattern is drawn, it takes about 100 gardeners about four hours to assemble the carpet, which is 77 x 24 metres.
