Check this out. The Annual Carpet of Flowers in the Grand-Place Brussels, Belgium. Close to a million begonia flowers are used to create this breathtaking spectacle. Craftsmen arrange the carpet by hand directly onto the square’s cobblestones without any soil. Grass and tree bark are also used to provide color. The first Carpet of Flowers was created in 1971 as a way to promote begonias. Each square meter of ground contains more than 300 flowers. Amazing!
