Tiny plants so small that they are hard to see with the naked eye.

Review of the eight smallest plant species in the world

Below are some of the smallest plant species in the world that we have gathered:

1. Rootless duckweed

Rootless duckweed (Wolffia angusta), is one of the smallest flowering plants in the world, with a size ranging from only 0.25 to 1 mm. They are often found on the surface of water and are commonly known as “fairy hair.” There are 38 species of duckweed in the world, and nine of them are among the smallest plants in terms of size. This plant prefers to live on the surface of water, but it has no roots.

Yes, Wolffia angusta, the rootless duckweed, can be used as a type of food as it contains nearly 50% of its dry weight as plant protein, similar to soybeans. In addition, it is also a favorite food of frogs, toads, and various species of fish.

Rootless duckweed is a plant species that is easy to find in ponds and lakes.

2. Tiny Orchid found in Brazil

One of the recently searched small plants is a type of orchid found in Brazil, which has a tiny size with its flower petals measuring only 0.5mm. Because of its small appearance, it is often mistaken for a weed until it blooms and its existence is finally recognized.

Despite its small size, this flower has demonstrated its resilience compared to larger plants. It continues to grow and bloom, spreading its fragrance far and wide.

Tiny orchids are one of the rarest flower species.

3. Water fern

Also known as Azolla, is one of the smallest aquatic plants in the world. They have a wedge-shaped form and their leaves are a vibrant shade of blue-green. What’s special about them is that they prefer to grow under water to sprout and develop in the best possible way, so the roots of this plant species are always submerged in water and easily symbiotic with blue-green algae to perform the process of nitrogen conversion from the air.

With a size of about 1 to 2 cm, it is used as food for pigs, chickens, and can also be used to treat wastewater. In general, Azolla and other types of aquatic ferns have practical applications for human life and animal husbandry.

The parva dwarf plant is known for its small appearance.

So what is the significance of these small plants in life?

The important role of small plants

The natural world is home to the smallest plant species that surprise and amaze us. Despite their small size, these plants play an important role in the natural ecosystem and are an essential part of the biodiversity of the Earth.

These small plants also contribute to their use in the research of scientists, which has important ecological significance. The way these species absorb water also helps to optimize and effectively treat wastewater and clean up water environments.

In addition, some small plant species have important significance in medicine by contributing to the improvement of kidney and liver issues in humans. They help to create a more beautiful, healthy environment and are a beautiful symbol of the resilience of small yet strong existence overtime.

Small plant species have contributed greatly to the diversity of ecosystems.

Above are small plant species, do you know how many species of plants are listed above? With the small and cute, resilient life of these plant species, we can feel how diverse and rich nature is.
