A bouquet of a dozen Wolffia blooms would comfortably fit on the head of a pin.
A type of duckweed, Wolffia grows on the surface of ponds and slow moving streams.
This very minute flowering plant is native to Australia and Malaysia. The plant body is 0.6-0.9 mm long and only 0.2-0.5 mm wide. Not only is it one of the smallest flowering plants on earth, but it also produces one of the smallest fruits.
