The largest flower mural, using 770,000 fresh dahlias, measured 1,868.94 m² (20,117ft²) and was created on 7 August 2001 by 1,250 people representing 16 neighbourhoods from the Dahlia Record Committee in Lemelerveld, The Netherlands.

The mural used 770,000 fresh dahlias which were glued on 900 individual panels. The panels were then all placed next to each other in a large square to make one continuous image. The mural was 6.03 m (19.78 ft) tall and 309.94 m (1,016.86 ft) long.
