Xanthosoma schunkei Croat

• Genus: Xanthosoma
• Botanical Background: Described by botanist Thomas B. Croat, the species honors Carlos Schunke, a Peruvian plant collector whose fieldwork contributed significantly to the discovery of several Amazonian species.

• Geographical Range: Endemic to Peru
• Environment: Occurs in warm, humid forests with rich, organic soils and consistent rainfall. Found in shaded understories with moderate to high humidity and ambient temperatures.

Leaves

• Broad, arrowhead-shaped (sagittate) leaves with smooth texture and dark green coloration
• Leaf blades are large and supported by long, upright petioles

Inflorescence (Spadix & Spathe)

• Inflorescence includes a pale green or yellowish spathe enclosing a thick spadix
• Pollinated by beetles, although specific data is limited

Growth Habit

• Terrestrial and tuberous, forming upright clumps
• Does not climb or produce runners and grows anchored in the forest floor

Light Requirements

• Bright, indirect light
• Should be protected from strong direct sunlight, especially during peak heat

Watering & Humidity

• Requires consistently moist but well-drained soil
• High humidity is ideal, mimicking its rainforest origin

Soil & Potting Mix

• Best in an organic-rich, airy mix
• Use a blend of peat, compost, and perlite for good drainage in containers

Temperature & Fertilizer

• Grows well at temperatures between 22–30°C (72–86°F)
• Fertilize monthly with a balanced or nitrogen-rich formula during the active growing season

Division

• Readily propagated by dividing the tuber
• Division should include at least one growing point

Seeds

• Propagation is uncommon and lacks extensive documentation
• Limited seed production in cultivation

Typical Issues

• Spider mites, aphids, and mealybugs
• Root or tuber rot can occur if overwatered

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap
• Prevent rot with good soil drainage and by avoiding overwatering

• Commemorates Carlos Schunke, who contributed to botanical exploration in Peru
• Remains a little-known but ecologically interesting specie

• Valued by aroid collectors for its rarity and bold tropical appearanc
• Not commonly cultivated, making it a sought-after species for specialty plant enthusiasts

Wild Population Status

• Not formally assesse
• Restricted range and habitat degradation in parts of the Peruvian Amazon suggest possible conservation concern

Market Availability

• Extremely rare in cultivation
• Found only in research institutions or private botanical collections
