Xanthosoma davidsmithii Croat & Delannay

• Genus: Xanthosoma
• Botanical Background: Described by botanists Croat and Delannay; Contributes to the diversity of Neotropical aroids. Their work has been key in distinguishing it from closely related species based on subtle morphological traits.

• Geographical Range: Indigenous to tropical rainforests of the Neotropics
• Environment: Thrives in warm and humid conditions with well-draining, organic soils. It grows naturally in shaded understories with filtered light and consistent ambient humidity

Leaves

• Uniquely shaped, offering a robust appearance
• Deep green coloration and prominent venation
• Form and texture add significant ornamental value

Inflorescence (Spadix & Spathe)

• Produces a typical aroid inflorescence with a pale spathe encasing a slender spadix
• Inflorescence, though modest in size, effectively attracts small insect pollinators

Growth Habit

• Terrestrial species that grows from a tuberous rhizome
• Forms dense clumps that are well suited for container cultivation and tropical understory gardens

Light Requirements

• Bright; indirect light
• Benefits from filtered light
• Should be shielded from direct sunlight to avoid leaf scorch

Watering & Humidity

• Maintain evenly moist soil without waterlogging
• High ambient humidity is essential
• Misting or situating the plant in a naturally humid area is recommended

Soil & Potting Mix

• A well-draining, organic-rich potting mix is preferred
• Blend of peat, perlite, and compost or coir provides the proper balance of moisture retention and drainage

Temperature & Fertilizer

• Growth occurs at temperatures between 20 and 28°C (68 and 82°F)
• Balanced, diluted fertilizer applied monthly during the growing season supports robust development

Division and Cuttings

• Division of the tuberous rhizomes
• Ensure each division includes ample roots and at least one active bud for successful growth

Seeds

• Less frequently practiced because germination rates
• Lower and the process is more time-consuming compared to division

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering may lead to fungal issues such as root rot

Treatment Recommendations

• Use insecticidal soap or neem oil to manage pest infestations
• Ensure proper air circulation
• Adjust watering practices to minimize the risk of fungal infections

• Named in honor of a contributor to aroid research
• Distinct leaf texture and shape are adaptations to its shaded tropical habitat and add to its visual interest

• Unusual foliage and compact clumping habit
• Adaptability to indoor tropical collections and shaded garden areas makes it a favored ornamental plant

Wild Population Status

• No immediate conservation concerns
• Ongoing habitat loss in tropical regions remains a potential long-term threat

Market Availability

• Available through specialist tropical plant nurseries and is favored by dedicated aroid collectors
• Relative rarity in mainstream horticulture increases its appeal
