• Genus: Lasimorpha 
• Botanical Background: Described by Heinrich Wilhelm Schott in 1855, Lasimorpha senegalensis was studied by early African botanists exploring aquatic flora.

• Geographical Range: Native to tropical West and Central Africa—from Senegal eastward through the Congo Basin to Uganda.
• Environment: Thrives in warm, shallow freshwater bodies (ponds, slow streams) with neutral to slightly acidic pH, high humidity (>70%), and soft, organic-rich substrates.

Leaves

• Peltate (stem attached centrally), circular, 10–25 cm diameter
• Glossy dark green upper surface, lighter underside
• Edges slightly undulate

Inflorescence (Spadix & Spathe)

• White spathe enclosing a short yellow spadix
• Fragrant during anthesis to attract aquatic pollinators (flies)
• Flowers emerge just above water surface

Growth Habit

• Free‑floating perennial with a short creeping rhizome
• Non‑rooted but may anchor lightly in soft sediment

Light Requirements

• Bright indirect to partial sun
• Tolerate full morning sun but avoid harsh afternoon rays to prevent leaf scorch

Watering & Humidity

• Maintain 5–15 cm of clean, warm water (20–28 °C)
• Humidity above 70% ideal

Soil & Potting Mix

• Grow in wide, shallow containers filled with aquatic substrate or fine gravel
• No traditional potting soil needed

Temperature & Fertilizer

• Optimal 22–30 °C 
• Feed monthly during growing season with diluted aquatic plant fertilizer

Division

• Easily propagated by dividing rhizome segments with at least one leaf node
• Replant immediately in water

Seeds

• Rarely used
• Viable seeds require warm (25–28 °C), shallow water and may take several weeks to germinate

Typical Issues

• Occasional aphids or snails
• Root rot if water becomes stagnant or anaerobic

Treatment Recommendations

• Manual removal of pests
• Use biological snail control
• Improve water circulation and perform partial water changes to prevent rot

• Unique among Araceae for fully floating habit
• Leaves provide shelter for aquatic invertebrates

• Valued in water gardens and botanical collections for its sculptural leaves and rarity in cultivation

Wild Population Status

• Currently not assessed by IUCN but potentially vulnerable to habitat degradation and water pollution

Market Availability

• Moderately rare
• Available through specialized aquatic plant nurseries and some botanical gardens
