Anthurium rosselianum Croat

• Genus: Anthurium
• Botanical Background: Described by the botanist Thomas B. Croat, a prominent figure in the study of aroids and his work continues to be influential in the classification of Araceae species.

• Geographical Range: Found in lowland to mid-elevation areas, typically found in shaded, moist environments.
• Environment: Prefers high humidity, well-drained soils, and temperatures ranging from 18-28°C; rainforest understories provide the ideal conditions for this species.

Leaves

• Heart-shaped
• Leathery
• Deep green color
• Medium-sized, reaching 30-40 cm in length
  
• Smooth, waxy surface
  
• Dark green with occasional subtle veins
  

Inflorescence (Spadix & Spathe)

• Spathe is white, surrounding a yellow spadix
• Compact, typically 4-5 cm long
• Mild scent

• Likely relies on insects for pollination, including flies attracted to the spadix

Growth Habit

• Terrestrial, growing in the forest floor's shady, moist conditions
• Supported by a short rhizome structure.

Light Requirements

• Best grown in bright, indirect light to mimic its natural environment under the forest canopy

Watering & Humidity

• Requires regular watering to keep the soil moist but not soggy
• Benefits from high humidity levels of 60% or more

Soil & Potting Mix

• Prefers a well-draining, organic-rich potting mix, such as one composed of peat, perlite, and bark

Temperature & Fertilizer

• Thrives in temperatures between 18-28°C
• Fertilize monthly during the growing season with a balanced, water-soluble fertilizer

Division

• Can be propagated by rhizome division or cutting mature stems with a node

Stem Cuttings (if applicable)

• Ensure cuttings are placed in a warm, humid environment to root successfully

Seeds

• Possible but not commonly practiced due to slow germination

Typical Issues

• Common pests include spider mites, aphids, and mealybugs
• Root rot may occur if overwatered or if drainage is inadequate

Treatment Recommendations

• Treat pest infestations with insecticidal soap or neem oil
• Ensure good drainage and remove affected roots

• Valued for its ornamental qualities, especially in tropical gardens and as an indoor plant

• Appreciated for its attractive, glossy leaves and compact growth
• Ideal for both small spaces and as part of tropical plant collections

Wild Population Status

• Currently not considered endangered, but habitat loss could affect its natural populations in the wild

Market Availability

• Found more often in specialty nurseries focused on aroids or tropical plants
• May require some searching or importing for those outside its native range
