Colocasia hassanii H.Ara

• Genus: Colocasia
• Botanical Background: Described by H.Ara, and its classification has been informed by the extensive work of botanists involved in the study of tropical aroids.

• Geographical Range: Native to select tropical regions where moist, warm climates prevail
• Environment: Thrives in rich, well-draining soils with consistent moisture. Its natural habitat includes lowland tropical forests and riverine areas where the climate is warm and humid.

Leaves

• Spadix surrounded by a spathe
• Not noted for a strong scent, the inflorescence adds to its botanical interest and aids in specialized pollination

Inflorescence (Spadix & Spathe)

• Grows as a terrestrial herb with a tuberous base
• Subtle, sometimes greenish spathe that may go unnoticed compared to showier species

Growth Habit

• Plant's robust rhizomes support its vigorous growth, making it adaptable to container gardening as well as ground planting

Light Requirements

• Performs best in bright, indirect light, replicating its natural understory habitat in tropical forests

Watering & Humidity

• Regular watering is essential
• Preference for high humidity
• Does well in consistently moist soil but should be protected from standing water to prevent root rot

Soil & Potting Mix

• A rich, well-draining potting mix that retains moisture
• Incorporating organic matter can help mimic its natural, fertile environment

Temperature & Fertilizer

• Optimal temperature range is between 65°F and 80°F
• Fertilize monthly during the growing season with a balanced liquid fertilizer

Division

• Dividing the tuberous base allows for successful propagation and is best done during repotting

Seeds

• Less common, propagation by seed is possible
• Seeds require warm, humid conditions to germinate and benefit from a controlled propagation environment

Typical Issues

• Spider mites, mealybugs, and occasional fungal root rot

Treatment Recommendations

• Gentle insecticidal soap or neem oil can be effective
• Improving air circulation and reducing excess moisture
• Appropriate fungicide treatments when necessary

• Unusual leaf morphology and robust growth habit
• Dramatic foliage and adaptability to both indoor and outdoor tropical garden settings

• Aesthetic appeal and ease of propagation make it a favored choice in ornamental horticulture

Wild Population Status

• No major conservation concerns

Market Availability

• Relatively rare in mainstream nurseries but can be sourced through specialty growers and botanical societies dedicated to aroids
