Introduction & Overview

Common and Scientific Names

  • Scientific Name: Anthurium angelamorae Croat
  • Common Name: Primarily known by this name, it may occasionally be referenced by variations in older literature, though no major synonyms are widely recognized

Quick Facts

  • Origin: From humid tropical regions of South America
  • Features: Glossy, heart-shaped leaves and subtly colored inflorescence 

Taxonomy & Classification

  • Genus: Anthurium
  • Botanical Background: First described by renowned botanist Thomas B. Croat, this species reflects a period of intensive exploration and classification of tropical aroids. Croat's work has been instrumental in expanding scientific knowledge of the Anthurium genus.

Natural Habitat & Distribution

  • Geographical Range: Native to the tropical forests of parts of South America, where it typically inhabits humid lowland and mid-elevation regions.
  • Environment: Thrives in environments with high humidity, well-draining organic soils, and a warm, stable climate with filtered sunlight under the forest canopy.

Morphological Characteristics

Leaves

  • Glossy, heart-shaped leaves
  • Medium to large size
  • Leathery texture
  • Often displaying subtle variegation or unique patterns

Inflorescence (Spadix & Spathe)

  • Slender spadix 
  • Modestly sized spathe that ranges from pale green to cream
  • Not strongly scented, the structure is well-adapted to its natural pollinators

Growth Habit

  • Typically terrestrial
  • Grows from a robust rhizome
  • Forms clumps that can gradually expand in size under optimal conditions

Cultivation & Care

Light Requirements

  • Bright, indirect light, that mimics the dappled sunlight of its native forest understory

Watering & Humidity

  • Regular watering is key to maintaining evenly moist soil
  • High ambient humidity is beneficial for healthy growth

Soil & Potting Mix

  • A well-draining, organic-rich potting mix is recommended, ideally amended with components like perlite or orchid bark to mimic its natural habitat

Temperature & Fertilizer

  • Prefers warm temperatures typical of tropical climates
  • Should be fed a balanced, diluted fertilizer monthly during the growing season

Propagation Methods

Division and Cuttings

  • Most common method is through division of the clumps, ensuring each section has a portion of the rhizome
  • Careful node cuttings can also be successful under controlled conditions

Seeds

  • Less common, but less common due to the specific germination requirements and the slow growth rate from seed

Common Pests & Diseases

Typical Issues

  • Spider mites and mealybugs
  • May be prone to fungal issues such as root rot if overwatered

Treatment Recommendations

  • Insecticidal soap or neem oil for pest control
  • Ensure proper air circulation along with a well-draining medium to prevent fungal infections

Notable Traits & Uses

  • Celebrated among collectors for its rarity and the distinctive character of its foliage and inflorescence, which make it a conversation piece in botanical circles
  • Unusual leaf shape and elegant inflorescence contribute to its high ornamental value
  • A prized specimen for dedicated tropical plant enthusiasts

Conservation & Availability

Wild Population Status

  • Ongoing concerns about its conservation status
  • Efforts are in place by local conservation groups to monitor wild populations

Market Availability

  • Relatively rare in cultivation
  • Usually available only through specialized collectors or botanical institutions
