Anthurium chacoense Croat

• Genus: Anthurium
• Botanical Background: First described by botanist Thomas B. Croat, who is well-known for his extensive work on the flora of the Aroid family, particularly in South America. Croat’s studies on this species helped establish its botanical identity in the 1980s.

• Geographical Range: Native to the Chaco region, spanning parts of Paraguay and adjacent areas of Argentina and Bolivia. Typically found in subtropical and tropical forests.
• Environment: Grows in humid environments with well-draining soils, often in regions that experience significant rainfall and mild temperatures; thrives at elevations ranging from 100 to 500 meters, where it enjoys indirect light and moderate warmth.

Leaves

• Large, leathery, and glossy
• Dark green with a heart-shaped appearance
• Can grow up to 30 cm long and 15 cm wide, with a pronounced central vein

Inflorescence (Spadix & Spathe)

• The spadix is white to pale green, surrounded by a long, white spathe
• Tends to be fragrant, attracting pollinators such as beetles
• Flower structure is typical of the genus, with the spathe serving to protect the spadix during its early stages

Growth Habit

• Primarily terrestrial, though some specimens may exhibit epiphytic traits
• Grows from a rhizome and has a relatively compact growth habit, making it suitable for indoor cultivation

Light Requirements

• Bright, indirect light
• Can tolerate some direct sunlight but may suffer from leaf burn if exposed too long

Watering & Humidity

• Requires regular watering, with the soil kept consistently moist but not soggy
• High humidity is essential for optimal growth
• Misting or placing it near a humidity tray can help meet this need

Soil & Potting Mix

• A well-draining, rich, organic soils, such as a mix of peat, perlite, and pine bark
• A loose, aerated potting medium will help prevent root rot

Temperature & Fertilizer

• Ideal temperatures range from 18°C to 27°C
• Balanced, diluted liquid fertilizer during the growing season (spring to summer)

Division

• Rhizome division

Stem Cuttings (if applicable)

• Cutting off a healthy portion with roots can help establish new plants
• Cuttings should be rooted in a humid environment with high warmth
  

Seeds

• Less common but can be successful with controlled conditions
• Require specific conditions to germinate, such as warm, moist, and shaded environments

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot is also a concern

Treatment Recommendations

• For pests, a systemic insecticide or neem oil can be used
• To prevent root rot, ensure the soil is well-drained and avoid letting the plant sit in water
• Fungicides can be applied if root rot becomes an issue
  

• Named for the Chaco region, reflecting its geographical origin
• Valued for its ornamental appeal and its ability to thrive in indoor environments with proper care

• Prized in horticulture for its striking leaves and inflorescence
• A popular choice for ornamental purposes in both homes and botanical gardens

Wild Population Status

• Currently, there are no significant conservation concerns though deforestation in its native range poses some risks to its natural habitat

Market Availability

• Not widely available in commercial markets and is generally considered a rare or specialty species
• Enthusiasts may need to look to niche sellers or collectors to obtain it
