Habitat: Floats on the surface of freshwater ponds and lakes.

Largest Flower: Rafflesia arnoldii.

The Smallest Flower in the World

The title for the smallest flower (and the smallest flowering plant) in the world goes to the Wolffia (commonly known as Watermeal).

  • Size: It is incredibly tiny. A single Wolffia plant is about the size of a grain of sand or a sprinkle you put on a cake (measuring about 0.1 to 0.2 millimeters in diameter).
  • Weight: It is so small and light that it would take roughly 5,000 of these flowers to weigh just one gram.

Fascinating Facts about Wolffia

  1. No Roots or Leaves: Unlike normal plants, Wolffia has no roots, stems, or true leaves. It is basically a tiny, floating green speck that sits on the surface of calm lakes and ponds.
  2. The Flower: The flower itself is microscopic. It grows in a tiny depression on the top of the plant and consists of just one pistil and one stamen.
  3. Highly Nutritious: Despite its microscopic size, it is packed with protein (like soybeans). In many parts of Asia, people actually collect it from the water and eat it as a nutritious vegetable.
