Background and Taxonomy:

• Lemnoideae, commonly known as Duckweed, belongs to the family Araceae.
• It’s one of the smallest flowering plants globally, often found floating on freshwater bodies.
• Taxonomically, Duckweed was once considered a subfamily of Araceae (Lemnoideae) but is now recognized as a separate family – Lemnaceae.
• There are five known genera of Duckweeds: Spirodela, Landoltia, Lemna, Wolffiella, and Wolffia.
• The most widespread species is Common Duckweed (Lemna minor), found across North America, Southeast Asia, and Europe.

Habitat and Adaptations:

• Duckweed thrives in freshwater ponds, slow-moving streams, and lakes worldwide.
• It can tolerate a wide range of water conditions, making it hardy and adaptable.
• Duckweed forms dense mats on the water surface, providing shade and performing essential ecological functions.

Care Guide for Duckweed:

1. Lighting: Duckweed grows well under medium to high light. It’s undemanding in terms of light intensity.
2. pH Range: Maintain a neutral pH between 6.5 and 7.5.
3. Water Hardness: Duckweed tolerates both soft and hard water.
4. Temperature: Keep the water temperature between 15°C and 32°C (60°F to 90°F).
5. Substrate: No substrate needed; it floats freely.
6. Growth Rate: Expect rapid growth; remove excess to prevent overcrowding.
7. Nutrients and CO2: Duckweed doesn’t require additional fertilizers or CO2.
8. Propagation: Divide healthy clumps for propagation.

Fun Fact:

• Duckweed owes its name to ducks. It sticks to their feathers and remains viable during flights, contributing to its global distribution.
