About Pale duckweed
Lemna valdiviana, commonly known as Pale Duckweed, is a tiny floating aquatic plant that forms dense green mats on the water's surface. Its small, pale green, oval fronds make it ideal for freshwater aquariums or small ponds where a natural and oxygenating plant cover is desired. It adds a touch of freshness, hides fry, and serves as an excellent biofilter.
Native range
North and South America
Care tips
It requires bright to moderate light for optimal growth, avoiding intense direct sunlight that could scorch the fronds. No substrate is needed as it floats freely, and it benefits from nutrient-rich water. It is crucial to control its proliferation, as it can quickly cover the entire water surface, blocking light from other plants. A common mistake is not pruning it regularly.
