Lemna minuta Kunth

• Genus: Lemna
• Botanical Background: Described by Kunth, this species has been the subject of ecological and botanical research, particularly in relation to its rapid reproduction and role in aquatic ecosystems.

• Geographical Range: Native to Europe, Asia, and North America
• Environment: Thrives in calm, nutrient-rich waters such as ponds, lakes, and slow-moving streams. Prefers warm temperatures, abundant sunlight, and low water turbulence.

Leaves

• Small, simple, oval green fronds that measure only a few millimeters across
• Smooth texture and slightly rounded margins

Inflorescence (Spadix & Spathe)

• Flowering structures are minimal and inconspicuous
• Produces tiny flowers under specific conditions that rarely contribute to its propagation

Growth Habit

• Aquatic, free-floating species that reproduces rapidly through budding, forming dense, mat-like colonies on the water surface

Light Requirements

• Bright, indirect light and can tolerate full sun in cooler environments

Watering & Humidity

• Maintaining consistent water levels
• Benefits from the high humidity typical of aquatic settings

Soil & Potting Mix

• Best grown directly in water enriched with nutrients
• Floating on the surface or using a water-based substrate

Temperature & Fertilizer

• Ideal water temperatures range from 15°C to 30°C
• Occasional use of diluted fertilizer

Division and Cuttings

• Propagation occurs mainly through vegetative reproduction
• New fronds bud off from the parent, allowing rapid colony expansion

Seeds

• Seed production is uncommon and is rarely used as a propagation method in cultivation

Typical Issues

• Algae overgrowth, snail infestations, and fungal infections

Treatment Recommendations

• Regular water changes, natural pest control, and maintaining balanced nutrient levels

• Extraordinary growth rate and its ability to remove excess nutrients from water.
• Simplicity and the insight it provides into aquatic plant physiology, as well as its ecological benefits.

Wild Population Status

• Widespread and not considered endangered

Market Availability

• Readily available in aquatic plant collections
• Commonly used in research and ornamental water gardens
