Xanthosoma scherberichii Croat & Delannay

• Genus: Xanthosoma
• Botanical Background: Described by botanists Thomas B. Croat and Bertrand Delannay, the species was named in honor of Jean-Pierre Scherberich, a French botanist associated with neotropical plant research.

• Geographical Range: Native to Colombia
• Environment: Grows in rich, well-drained soils with consistent rainfall and high ambient humidity

Leaves

• Large, sagittate leaves with smooth, dark green surfaces and well-marked venation
• Petioles are long and upright, supporting a broad leaf blade

Inflorescence (Spadix & Spathe)

• Spathe is pale green to cream-colored, surrounding a fleshy spadix
• Emits a mild scent and attracts beetle pollinators, as is typical of the genus

Growth Habit

• Terrestrial, tuberous species that forms upright clumps
• Does not climb or spread via runners, instead relying on tuber expansion

Light Requirements

• Bright, indirect light
• Avoid direct midday sunlight to prevent leaf damage

Watering & Humidity

• Requires evenly moist soil, especially during the growing season
• High humidity is essential to maintain healthy growth

Soil & Potting Mix

• Prefers a rich, well-draining mix composed of peat, compost, and perlite
• Ensure containers have adequate drainage holes

Temperature & Fertilizer

• Ideal temperatures range from 22–30°C (72–86°F)
• Feed monthly during active growth with a balanced, water-soluble fertilizer

Division

• Propagation is typically done by dividing the tubers
• Division should include a viable growth bud

Seeds

• Propagation is not common due to limited seed availability
• Lack of detailed germination studies

Typical Issues

• Spider mites, aphids, and mealybugs
• Poor drainage can result in root or tuber rot

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap
• Ensure good drainage and avoid overwatering to prevent fungal problems

• Named in recognition of Jean-Pierre Scherberich’s botanical contributions
• Species reflects the floristic richness of Colombia's tropical forests

• Rarely cultivated, its bold foliage and compact form
• Potential candidate for tropical garden collections or shaded greenhouse displays

Wild Population Status

• Not formally evaluated
• Limited range suggests potential concern if natural habitats continue to be altered or lost

Market Availability

• Extremely rare in cultivation
• Not typically available through commercial horticultural suppliers
