Anthurium dukei Croat

• Genus: Anthurium
• Botanical Background: Named and described by botanist Dr. Thomas B. Croat in 1983, Anthurium dukei is part of a larger group of tropical aroids. Dr. Croat, a prominent figure in the study of the Araceae family, has contributed greatly to the understanding of plant species in this genus

• Geographical Range:  Tropical rainforests of Panama and Costa Rica
• Environment: Thrives in high humidity and shaded environments. It naturally grows in rich, well-drained soils, often near the forest floor or in slightly elevated areas where moisture is abundant

Leaves

• Large, lance-shaped
• Glossy
• Deep green coloration and prominent veins
• Create a textured, almost leathery feel

Inflorescence (Spadix & Spathe)

• The flower structure of Anthurium dukei features a typical spadix and spathe arrangement, with a striking red spathe that contrasts beautifully with the white spadix. The spathe is roughly 8–10 cm in length and attracts pollinators with its subtle scent

Growth Habit

• It is a terrestrial species, typically growing in dense forest undergrowth. Anthurium dukei does not exhibit epiphytic tendencies, unlike some other members of the Anthurium genus

Light Requirements

• Provide bright, indirect light for optimal growth. Direct sunlight can scorch the leaves, leading to damage

Watering & Humidity

• Water regularly, ensuring the soil remains consistently moist but not waterlogged. High humidity (60% or above) is crucial for healthy growth. Mist the plant or use a humidity tray to maintain moisture

• A well-draining, organic-rich potting mix is ideal. Consider using a mix designed for aroids, incorporating peat, perlite, and pine bark to ensure proper drainage

Temperature & Fertilizer

• Maintain temperatures between 18–26°C (65–79°F)
• Fertilize monthly during the growing season with a balanced, water-soluble fertilizer diluted to half strength
  

Division and Cuttings

• Propagate by division or by taking stem cuttings with a node and aerial roots. Ensure the cutting is at least 5–10 cm long with a node for successful rooting

Seeds

• While propagation by seeds is possible, it is not commonly done due to the species' rarity in cultivation. If attempting, seeds should be sown in a warm, moist environment to encourage germination

Typical Issues

• Spider mites; mealybugs and aphids
• Root rot
  

Treatment Recommendations

• For pests, use insecticidal soap or neem oil. If root rot occurs, repot the plant in fresh, well-draining soil and cut away any affected roots. For pest infestations, treat promptly with organic insecticides

• Anthurium dukei is often admired for its ornamental qualities, and it holds a unique position within the aroid community due to its striking inflorescence and glossy foliage. It is sometimes used in traditional medicine in its native range, though this usage is not widespread

• This species is valued by collectors for its rarity and elegance. Its vibrant spathe and resilient nature make it a sought-after plant in aroid collections

Wild Population Status

• There are no significant conservation concerns, though habitat destruction in Central America poses a potential threat to its natural populations. It is not classified as endangered

Market Availability

• Anthurium dukei is not commonly found in the market due to its limited range and slow cultivation process. It is considered rare, often found only in specialist aroid collections
