Duck lettuce - Ottelia alismoides (Taxonomy, Characteristics, Distribution, Images)

Duck lettuce

Also known as: Ottelia

Duck lettuce is a fully submerged aquatic plant that is usually found in still water, such as rice fields or ponds. It is occasionally found in slow-flowing bayous. This slow-spreading annual is occasionally confused with the Water Trumpet or Water Plantain but is distinguished by its noticeable cross-ribbing on submerged leaves. The seeds of this herb are a food source for fish.

Water: Originating from warm, stagnant waters in Asia and Africa, duck lettuce thrives in high humidity and can regulate its water content when submerged. It needs weekly watering for consistent moisture and often grows outdoors, using unique adaptations to optimize underwater photosynthesis and maintain hydration.

Fertilize: For optimal growth of duck lettuce, apply balanced-nutrition fertilizers monthly during the growing season, using half the recommended dose for aquatic types. In winter, reduce applications due to slowed growth. Dilute and distribute fertilizer near the roots to enhance duck lettuce's health and appearance.

Pruning: Duck lettuce thrives in aquatic environments and benefits from careful pruning during early to late spring. Removing dead leaves enhances water quality and prevents disease, while regular maintenance promotes healthy growth and optimal sunlight access, preserving both its beauty and ecological balance in water gardens.

Propagation: Duck lettuce can be propagated by collecting healthy seeds and sowing them in moist, soil-rich mediums underwater. Ensure seeds are not buried deeply to allow light for germination. Regular moisture monitoring encourages growth, helping duck lettuce thrive in water gardens.
