Xanthosoma reinae Croat & Delannay

• Genus: Xanthosoma
• Botanical Background: Described by botanists Thomas B. Croat and Henri Delannay; Named after its notable leaf structure and its role in the rainforests of Panama. This species was studied for its unique morphological traits and its ornamental potential.

• Geographical Range: Native to the tropical rainforests of Panama
• Environment: Requires consistently high humidity and rich, well-draining soils. It grows naturally in shaded forest understories, where it benefits from indirect light and moderate rainfall

Leaves

• Large, heart-shaped, and leathery with a deep green coloration
• Texture is thick and robust, helping the plant retain moisture in its humid native environment
• Leaves can grow up to 60 cm long

Inflorescence (Spadix & Spathe)

• Spathe is pale green, enclosing a small spadix
• Flowers are modest, not typically valued for ornamental appeal
• Pollinated by insects attracted to the spadix

Growth Habit

• Terrestrial plant that grows from a rhizome
• Produces upright stems and large leaves that emerge from the base, giving the plant a bushy appearance
• It does not climb or trail

Light Requirements

• Bright; indirect light
• Too much direct sunlight can damage the leaves, so it should be placed in an area with filtered light

Watering & Humidity

• Requires consistently moist soil and thrives in high humidity
• Should be watered regularly, ensuring the soil remains moist but not waterlogged
• Humidity levels of 60% or higher are ideal for growth

Soil & Potting Mix

• A well-draining, rich potting mix is essential
• Mixture of peat, perlite, and orchid bark works well to retain moisture while allowing for good drainage
• Container with drainage holes is essential to avoid water retention at the roots

Temperature & Fertilizer

• Ideal temperature range is between 20°C and 30°C
• During the growing season, should be fed monthly with a balanced, water-soluble fertilizer to encourage healthy foliage growth

Division

• Typically propagated by division
• When becomes large enough, the rhizomes can be divided into smaller sections, each containing roots and shoots

Seeds

• Propagation is possible but not commonly practiced
• Should be sown in a warm, humid environment
• Germination can take several weeks

Typical Issues

• Aphids, mealybugs, and spider mites
• Root rot can also be an issue if the plant is overwatered or if the soil retains too much moisture

Treatment Recommendations

• Insect pests can be controlled using insecticidal soap or neem oil
• For root rot, improve soil drainage, reduce watering frequency, and repot the plant if necessary
• Trim affected roots and place the plant in fresh, well-draining soil

• Contributes to the biodiversity of tropical rainforests and plays a role in the local ecosystem
• Used as an ornamental species, it is also valued for its ability to thrive in low-light, humid environmentss

• Large, leathery leaves, making it a favorite for tropical gardens, indoor plants, and collectors of aroids
• Ability to thrive in low-light conditions adds to its appeal for shaded areas

Wild Population Status

• Does not currently face significant conservation threats
• Habitat loss due to deforestation

Market Availability

• Not widely available in mainstream garden centers 
• Found in specialty nurseries or online plant retailers that focus on tropical plants
