Xanthosoma sagittifolium (L.) Schott

• Genus: Xanthosoma
• Botanical Background: Originally described by Carl Linnaeus as Arum sagittifolium, it was later reassigned to Xanthosoma by Heinrich Wilhelm Schott, a prominent aroid taxonomist.

• Geographical Range: Native to northern South America and Central America
• Environment: Thrives in warm, humid climates with well-drained, fertile soils and grows best in tropical lowlands, often cultivated in fields, gardens, or near water sources.

Leaves

• Large, sagittate (arrow-shaped)
• Smooth margins and a bright to deep green color
• Can reach over 1 meter in length and are held on long petioles

Inflorescence (Spadix & Spathe)

• Inflorescence consists of a pale green to yellowish spathe surrounding a short, stout spadix
• Emits a mild scent and is typically pollinated by beetles

Growth Habit

• Robust, terrestrial species with an underground tuber
• Forms dense clumps and grows upright

Light Requirements

• Prefers full sun to partial shade
• Bright indirect light is ideal in indoor settings

Watering & Humidity

• Needs regular watering, especially in dry seasons or during active growth
• High humidity promotes healthy leaf development

Soil & Potting Mix

• Grows well in rich, well-draining soils with organic matter
• Containers, a mix of compost, peat, and sand or perlite works well

Temperature & Fertilizer

• Optimal temperature range is 22–30°C (72–86°F)
• Feed with a balanced fertilizer every 2–4 weeks during the growing season

Division

• Commonly propagated via division of the corms or tubers
• Division should contain an eye or bud for sprouting

Seeds

• Propagation is rare
• Reserved for breeding or research purposes due to low viability and slow germination

Typical Issues

• Aphids, mealybugs, and spider mites
• Corm rot can occur in poorly drained soils

Treatment Recommendations

• Use insecticidal soap or neem oil to manage pests
• Avoid overwatering and ensure good drainage to prevent rot

• Corms are a traditional food source in many tropical cultures and are typically boiled or fried
• Raw consumption is toxic due to calcium oxalate crystals

• Bold foliage makes it a popular ornamental plant in tropical gardens or large indoor spaces
• Fast growth and dramatic leaf shape are particularly attractive

Wild Population Status

• Not currently under threat
• Wide distribution and agricultural use, it is not considered at risk in the wild

Market Availability

• Widely available as both a food crop and ornamental plant
• Sourced from nurseries, garden centers, and markets in tropical and subtropical regions
