Anthurium grandicataphyllum Croat & M.M.Mora

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and M.M.Mora, Anthurium grandicataphyllum has garnered attention in botanical circles for its distinctive features. Its formal identification has contributed to a broader understanding of aroid diversity in neotropical ecosystems

• Geographical Range: Indigenous to tropical areas of South America
• Environment: Thrives in high humidity and well-drained, organic-rich soils. It usually grows in shaded understories where temperatures remain relatively stable throughout the year

Leaves

• Leaves are large and broadly lanceolate
• Textured surface
• Lossy finish.
• Coloration ranges from deep green
• Hints of variegation in some specimens, contributing to the plant's ornamental value

Inflorescence (Spadix & Spathe)

• The inflorescence consists of a vibrant spathe paired with a slender spadix. While the spathe is typically a muted tone complementing the leaf color, it plays an essential role in attracting pollinators through both visual cues and subtle scents

Growth Habit

• Typically terrestrial, this aroid exhibits a rhizomatous growth habit that allows it to form clumps over time. Its robust roots enable it to thrive both in natural forest floors and in controlled container environments

Light Requirements

• Best grown in bright, indirect light, Anthurium grandicataphyllum benefits from filtered sunlight that mimics its native forest understory

Watering & Humidity

• It requires consistent watering to maintain moist soil conditions without becoming waterlogged. High humidity levels are ideal, and regular misting can be beneficial in drier environments

• A well-draining, organic-rich potting mix is recommended. Containers with good drainage help prevent root rot and mimic the plant’s natural conditions

Temperature & Fertilizer

• This species thrives in temperatures ranging from 65°F to 80°F
• A balanced, diluted fertilizer applied during the growing season supports healthy growth without overwhelming its roots

Division and Cuttings

• Propagation is most commonly achieved through rhizome division. Carefully separating clumps during repotting encourages the development of new growth without causing undue stress

Seeds

• While seed propagation is possible, it is less frequently practiced due to longer germination times and variable viability compared to division methods

Typical Issues

• Spider mites and mealybugs
• Root rot
  

Treatment Recommendations

• When pests are detected, treatments such as insecticidal soap or neem oil are effective. Ensuring proper drainage and avoiding excessive watering are key strategies to mitigate fungal diseases

• While detailed conservation assessments are limited, habitat loss in tropical regions underscores the need for careful cultivation and conservation efforts

• This species is relatively rare in cultivation. It is sought after by dedicated collectors, and its limited availability often makes it a prized addition to specialized plant collections

Wild Population Status

• While not currently listed as endangered, habitat loss in its native range is a concern, prompting interest in conservation initiatives

Market Availability

• Anthurium grande is generally available through specialty nurseries and botanical collections, though it may be less common than some other Anthurium species
