Anthurium haltonii Croat

• Genus: Anthurium
• Botanical Background: Described by renowned aroid botanist Dr. Thomas B. Croat, a leading authority on the genus Anthurium. The species was named in honor of Richard Halton, a former research associate

• Geographical Range: Endemic to Panama
• Environment:  It grows in humid, tropical conditions, typically as an epiphyte on tree trunks in lowland wet forests. It thrives in high humidity, warm temperatures, and filtered light

Leaves

• Narrow, lanceolate
• Coriaceous (leathery
• Smooth margins
• Glossy to semi-glossy finish
• Leaves can reach over 30 cm in length

Inflorescence (Spadix & Spathe)

• The spathe is slender and can range in color from pale green to reddish-purple, while the spadix is typically slender and pendant. Little fragrance is noted, and pollination is likely carried out by beetles or small flies

Growth Habit

• Epiphytic, growing on trees in its natural habitat. It features a climbing growth habit supported by aerial roots emerging from nodes along the stem

Light Requirements

• Prefers bright, indirect light. Avoid direct sun, which can scorch the leaves

Watering & Humidity

• Keep consistently moist but not soggy. High humidity (above 60%) is ideal for optimal growth

Soil & Potting Mix

• Use a well-draining, chunky aroid mix—typically a combination of orchid bark, perlite, sphagnum moss, and a small amount of rich organic matter

Temperature & Fertilizer

• Ideal temperatures range from 65–85°F (18–29°C)
• Feed with a balanced, diluted fertilizer every 4–6 weeks during the growing season

Division and Stem Cuttings

• Best propagated through stem cuttings with aerial roots or by dividing a mature plant. Each cutting should include at least one node

Seeds

• Propagation by seed is possible but uncommon and slow. Seeds must be sown fresh on a moist, sterile medium

Typical Issues

• Spider mites and mealybugs
• Thrips
• Fungal root rot

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap. Ensure good air circulation and proper watering habits to prevent fungal issue

• The species is rarely seen in cultivation and is of interest primarily to specialized collectors. It has no known cultural or folkloric uses

• Highly valued for its elegant, narrow leaves and understated inflorescence. It makes an excellent addition to rare tropical plant collections

Wild Population Status

• Due to its limited range, Anthurium haltonii may face habitat pressure from deforestation. However, it has not been assessed for the IUCN Red List

Market Availability

• Considered rare in cultivation and typically found only through specialized growers or plant exchanges
