Xanthosoma oyuelae Croat & Delannay

• Genus: Xanthosoma
• Botanical Background: First described by Thomas Croat and Delannay; Named after the Oyuela region in Colombia. Croat is a renowned botanist who has made significant contributions to the taxonomy of Aroids.

• Geographical Range: Native to the tropical rainforests of Colombia and Ecuador
• Environment: Prefers high humidity and moderate temperatures, typical of the tropical rainforest climate. It grows best in soils that retain moisture but drain well, in environments with consistent rainfall.

Leaves

• Large, arrow-shaped, and glossy, with a deep green color
• Texture is leathery, which helps the plant cope with the humid environment it grows in

Inflorescence (Spadix & Spathe)

• Inflorescence is typical of other Xanthosoma species: it features a spadix surrounded by a greenish spathe
• Flowers are not particularly showy, relying on insect pollinators for reproduction

Growth Habit

• Terrestrial plant that forms dense clumps
• Has a rhizomatous root system, allowing it to spread and form a large colony under optimal conditions

Light Requirements

• Bright; indirect light
• Direct sunlight should be avoided, as it can scorch the leaves

Watering & Humidity

• Regular watering is necessary to keep the soil moist but not soggy
• High humidity is crucial for optimal growth
• Should be misted regularly if grown indoor

Soil & Potting Mix

• Well-draining soil that retains moisture but does not become waterlogged
• A mixture of peat, perlite, and bark works well for this species

Temperature & Fertilizer

• Thrives in temperatures ranging from 20–30°C (68–86°F)
• Growing season, use a balanced fertilizer once a month to encourage vigorous growth and healthy foliage

Division

• Propagation is division, where rhizomes are separated and planted as individual plants
• Division should have healthy roots and shoots to ensure successful growth

Seeds

• Propagation is possible but less common
• Should be sown in moist soil and kept in a warm, humid environment for germination

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot is a potential issue if the soil is too wet or lacks proper drainage

Treatment Recommendations

• Insecticidal soap or neem oil can effectively manage pests
• Prevent root rot, ensure proper drainage and avoid overwatering
• Fungal issues arise, use a fungicide to treat the plant

• Primarily ornamental, Plays a role in its native habitat by contributing to the biodiversity of the rainforest floor
• Large, glossy leaves are a notable feature in any tropical garden

• Large, arrow-shaped, glossy leaves make it a striking addition to any tropical garden or indoor collection
• Exotic appearance and relatively low maintenance requirements make it a favorite among plant enthusiasts

Wild Population Status

• No immediate conservation concerns
• Habitat in tropical rainforests is threatened by deforestation

Market Availability

• Not as widely available
• Can be found in specialized nurseries that focus on rare and ornamental tropical plants
