Anthurium dorbayae Croat

• Genus: Anthurium
• Botanical Background: First described by botanist Thomas B. Croat in 1977, A. dorbayae was named after the region where it was discovered, contributing to the expanding knowledge of Panamanian flora. Croat's work on the genus Anthurium remains foundational in understanding its diverse species

• Geographical Range: Native to the cloud forests of western Panama
• Environment:  It naturally thrives at high altitudes in shaded, moisture-rich environments with well-draining soil. The species requires high humidity and moderate temperatures to flourish

Leaves

• Broad, glossy
• Deep green
• Distinctive heart-shaped or slightly ovate appearance
• Surface is smooth, with some species showing faint venation patterns

Inflorescence (Spadix & Spathe)

• The spathe is a deep green, sometimes tinged with purple, while the spadix is yellow, making for an attractive contrast. The inflorescence is not particularly large but is highly prized for its color and form. Pollination is facilitated by the movement of insects attracted to the spadix's subtle scent

Growth Habit

• This species is terrestrial and grows as a small shrub or understory plant. It develops rhizomes that allow it to spread slowly in its native habitat

Light Requirements

• Anthurium dorbayae does best in bright, indirect light. Direct sunlight may scorch its leaves, while too little light can result in poor growth

Watering & Humidity

• Regular watering is essential to maintain moisture levels, especially in warmer weather. It thrives in high humidity, often requiring supplemental misting or humidity trays in dry climates

• A well-draining, organic-rich potting mix is ideal for this species, such as a blend of peat, pine bark, and perlite. The soil should retain moisture without becoming waterlogged

Temperature & Fertilizer

• Optimal temperature ranges between 65-85°F (18-29°C)
• During the growing season, feeding with a balanced, liquid fertilizer every 4-6 weeks encourages healthy growth
  

Division and Cuttings

• Propagation is most commonly done by dividing the rhizomes or taking stem cuttings, ensuring each section has at least one node. Rooting hormone can improve success rates for cuttings

Seeds

• Although seed propagation is possible, it is not commonly practiced due to the relatively low germination rate and the long time it takes for the seeds to mature

Typical Issues

• Spider mites and mealybugs aphids
• Overwatering may lead to root rot

Treatment Recommendations

• Insecticidal soap or neem oil can be used for pests, while ensuring good drainage can help prevent root rot. Fungal infections can be treated with fungicides, especially in humid environments

• The species is named after its unique origin, dorbayae referring to the region of discovery. It is a rare find in the wild and is of interest to conservationists due to its limited range

• Anthurium dorbayae is prized for its ornamental leaves and striking inflorescence. It makes an excellent addition to tropical or subtropical gardens, particularly in shaded areas with good humidity

Wild Population Status

• There are no significant conservation concerns currently, but its limited geographical range means it could be susceptible to habitat loss. Conservation efforts focus on maintaining its cloud forest habitat

Market Availability

• Anthurium dorbayae is not widely available in mainstream markets, being more of a specialty plant among collectors and aroids enthusiasts
