Lemna minuta aka Least Duckweed

Taxonomy

Lemna minuta, also known as least duckweed, is the smallest species of Lemna. While its exact native range is not known, it is native to parts of the Americas and has been naturalized in other regions, including Europe where it has been spreading and is considered a noxious weed in some areas like Belgium. This aquatic plant grows in slow-moving, stagnant freshwater habitats, where it forms mats on the water surface, reducing sunlight penetration and oxygen exchange. The plant's shape varies depending on growth conditions, with shade-grown plants often having slightly longer, more transparent thalli that sometimes grow in connected clusters of up to four plants. In contrast, plants grown in full sunlight generally grow in pairs. Lemna minuta produces ephemeral, membrane-bound flowers and is typically found in direct light less than 1 foot away from a window. To thrive, it needs regular watering and well-draining soil, as well as gentle, organic fertilizer during the peak growing season.

How to care for Least Duckweed

Difficulty

Least Duckweed is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Least Duckweed should be watered regularly, allowing the soil to dry out between waterings.

Soil

Least Duckweed loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Least Duckweed requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Least Duckweed will be sure to bring you many years of beauty and enjoyment.
