Anthurium arbelaezii Croat

• Genus: Anthurium
• Botanical Background: Described by Croat, this species has been influential in studies of Anthurium diversity, reflecting ongoing efforts by botanists to understand the evolutionary relationships within the group

• Geographical Range: Indigenous to parts of South America.
• Environment:  In its natural setting, the plant thrives under high humidity, in well-draining, organic-rich soils, and within a consistently warm climate that mimics the understory of tropical forests

Leaves

• Large,  heart-shaped leaves
• Leathery in texture
• Deep green coloration
• Rich green color that can captivate the eye

Inflorescence (Spadix & Spathe)

• Colorful spathe that provides a dramatic contrast to the foliage.
• Does not emit a strong scent, insect pollinators are believed to play a role in its reproduction

Growth Habit

• Terrestrial species grows via a rhizomatous network

• Often forming clumps that contribute to its robust, bush-like appearance

Light Requirements

• Bright, indirect light, simulating the dappled sunlight found in its native forest understory

Watering & Humidity

• Regular watering is essential to keep the soil consistently moist but not soggy
• High ambient humidity is beneficial, aligning with its tropical origins

Soil & Potting Mix

• A loose, well-draining mix enriched with organic matter is ideal
• A specialized aroid blend often works best to support its growth

Temperature & Fertilizer

• Optimal temperature range is between 65–80°F (18–27°C)

• Balanced fertilizer applied during the growing season aids in maintaining vigorous growth

Division & Cutting

• Most common propagation method is through division of the rhizomes, ensuring that each segment has ample roots and shoots to develop into a mature plant

Seeds

• Less frequently employed due to variable germination rates

• Successful seed sprouting typically requires warm conditions and high humidity

Typical Issues

• Spider mites and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Preventive measures include ensuring proper drainage and using organic insecticides
• Integrated pest management techniques to control infestations

• Admired not only for its beauty but also for its contribution to scientific studies on aroid diversity 

• Often featured in botanical displays and specialized plant collections

• Prized for its dramatic leaf shape and striking spathe, making it a standout piece in tropical and ornamental plant collections

Wild Population Status

• Habitat loss in tropical regions poses potential risks to its wild populations

Market Availability

• Typically available only through specialized nurseries and is highly sought after by dedicated collectors
