Anthurium guatemalense Croat, Cast.Mont & Vannini

• Genus: Anthurium
• Botanical Background: This species was described by renowned botanists Croat, Cast.Mont, and Vannini, who contributed to the modern understanding of Central American aroids through extensive field studies and herbarium research

• Geographical Range: Tropical rainforests in Central America
• Environment: It naturally grows in humid, shaded understory environments with well-drained, organically rich soils. The species prefers consistently moist conditions and moderate temperatures typical of tropical forests

Leaves

• Boasts large, glossy leave
• Leathery leaves
• Leathery texture and a deep green coloration
• Shape is often broad with slightly undulating margins

Inflorescence (Spadix & Spathe)

• It produces a striking inflorescence, where a spathe of contrasting hues encases a slender spadix. Though not typically scented, the coloration and structure play a role in attracting specific pollinators

Growth Habit

• Terrestrial species that develops from a rhizome. It exhibits a clumping growth pattern and can occasionally form aerial roots when grown in its natural, humid habitat

Light Requirements

• For optimal growth, provide bright, indirect light. Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Water regularly to maintain consistently moist soil, ensuring the plant does not sit in stagnant water. High humidity levels are ideal, reflecting its native tropical conditions

Soil & Potting Mix

• A well-draining potting mix rich in organic matter is preferred. A blend containing peat, perlite, and orchid bark mimics the natural forest floor and supports healthy root development

Temperature & Fertilizer

• Maintain a warm temperature range (ideally between 65°F and 80°F)

• Feed with a balanced, water-soluble fertilizer every 4 to 6 weeks during the growing season to support active growth

Division & Cutting

• The most common method of propagation is through division of the rhizomes. Carefully separating clumps during repotting can yield new plants

Seeds

• While propagation by seed is possible, it is less common due to variable germination rates and a longer time to maturity

Typical Issues

• Spider mites
• Mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Regular monitoring and the use of organic pesticides such as neem oil can help manage pest issues. Ensure proper air circulation and watering practices to minimize disease risks

• Plays a role in local ecosystems and has inspired interest among collectors due to its distinctive foliage and inflorescence. Its discovery has enriched the botanical understanding of Central American aroids

• This species is prized for its bold appearance and unique leaf structure, making it a popular choice for both indoor and greenhouse collections. Its rare attributes often attract dedicated hobbyists and professional cultivator

Wild Population Status

• While detailed conservation assessments are still ongoing, habitat loss in tropical regions raises concerns for its wild populations. Conservation efforts are in place in some regions to preserve native aroid species

Market Availability

• Due to its specific growing requirements and limited natural distribution, Anthurium guatemalense is considered rare and highly valued by collectors and enthusiast
