Anthurium hartmanii Croat & O.Ortiz

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and O. Ortiz, Anthurium hartmanii contributes to the rich diversity of aroids.; its description highlights the increasing documentation of tropical plant species by experts dedicated to understanding rainforest biodiversity.

• Geographical Range: Native to tropical regions of South America where it is found in lowland to mid-elevation rainforests; its precise distribution may be localized, reflecting the unique ecological niches within these biodiverse areas.
• Environment: Hhigh humidity, warm temperatures, and dappled light typical of forest understories; it grows on well-draining, organic soils that are enriched by decomposing plant matter.

Leaves

• Broad and heart-shaped leaves
• Glossy texture and deep green coloration
• Moderately sized

Inflorescence (Spadix & Spathe)

• Notable inflorescence comprising a contrasting spathe and a central spadix
• Spathe often displays vibrant hues that serve to attract specialized pollinators
• Spadix is relatively cylindrical and supports numerous small flowers

Growth Habit

• Epiphytic habit
• Anchors on trees, or occasionally grow terrestrially
• Develops rhizomatous roots

Light Requirements

• Bright, indirect light
• Direct sunlight should be avoided to prevent leaf burn

Watering & Humidity

• Regular watering
• Moist without waterlogging
• High humidity

Soil & Potting Mix

• A well-draining mix composed of peat, perlite, and organic matter
• Containers should allow for ample drainage

Temperature & Fertilizer

• Temperatures range between 65°F and 80°F (18°C to 27°C)

• A balanced, water-soluble fertilizer applied during the active growing season

Division and Stem Cuttings

• Most effective propagation method is by dividing the rhizomes during repotting
• Node cuttings from the stems can also be used
• Proper moisture and temperature conditions are maintained

Seeds

• Require warm, humid conditions and may benefit from a period of stratification to enhance germination

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Careful adjustment of watering routines
• Organic fungicides

• Unique leaf architecture and contrasting inflorescence

• Supports biodiversity by providing microhabitats for small organisms

• Aesthetic appeal
• Bold leaf shape and eye-catching inflorescence enhance indoor collections and specialized tropical displays

Wild Population Status

• Population studies are limited
• Habitat loss in tropical regions is a concern

Market Availability

• Uncommon in commercial nurseries
• Availability primarily through specialist collectors and botanical exchanges
• Rare and often adds to its allure in the horticultural community
