Xanthosoma davidsonii Croat

• Genus: Xanthosoma
• Botanical Background: Described by botanist Croat; Contributes to our understanding of Neotropical aroid diversity. Early studies on the morphological variations within Xanthosoma have helped establish its identity as a unique species in this complex group.

• Geographical Range: Native to tropical rainforests in the Neotropics
• Environment: Thrives in warm, humid conditions with rich, well-draining soils. It is typically found in shaded understory habitats where filtered light and consistent moisture promote robust growth.

Leaves

• Distinctly shaped, medium to large in size, and exhibit a textured surface
• Deep green coloration
• Pronounced venation and may display subtle patterns 

Inflorescence (Spadix & Spathe)

• Produces an inflorescence typical of aroids, with a pale spathe encasing a slender spadix
• Modest in size and is adapted to attract small insect pollinators

Growth Habit

• Terrestrial plant that grows from a tuberous rhizome
• Forms dense clumps, an adaptation that aids in its survival in competitive tropical understory environments

Light Requirements

• Bright; indirect light
• Performs best in filtered light conditions
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Regular watering is necessary to keep the soil evenly moist without causing waterlogging
• High ambient humidity is critical
• Misting or placing the plant in a naturally humid environment is recommended

Soil & Potting Mix

• A well-draining, organic-rich potting mix is preferred
• Blend of peat, perlite, and compost or coir provides a balanced mix that retains moisture while allowing excess water to drain

Temperature & Fertilizer

• Maintain temperatures between 20 and 28°C (68 and 82°F) to mimic its native tropical conditions
• Balanced, diluted fertilizer applied monthly during the growing season will support vigorous growth

Division

• Dividing the tuberous rhizomes
• Division should include an adequate portion of roots and at least one active bud to ensure successful establishment

Seeds

• Less common due to lower germination rates
• Longer time required for the plant to reach maturity compared to division

Typical Issues

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

Treatment Recommendations

• Manage pests with insecticidal soap or neem oil
• Ensure proper air circulation
• Adjust watering practices to prevent fungal diseases and maintain overall plant health

• Plays a role in the tropical understory ecosystem by contributing to biodiversity
• Unique leaf shape may serve as an adaptation to low-light conditions and helps differentiate it from related species

• Striking foliage and compact, clumping growth habit
• Ability to thrive in indoor collections and shaded tropical gardens makes it a valued ornamental plant

Wild Population Status

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

Market Availability

• Available through specialist tropical plant nurseries and dedicated aroid collectors
• Relative scarcity in mainstream horticulture increases its desirability among enthusiasts
