Anthurium kallunkiae Croat

• Genus: Anthurium
• Botanical Background: Named by renowned botanist Thomas B. Croat, the species has been of particular interest in studies of tropical aroids; its description has contributed to a broader understanding of Anthurium diversity and evolution.

• Geographical Range: Indigenous to tropical regions of South America, where it naturally occurs in humid, shaded forest understories.
• Environment: Environments with high humidity and well-draining, organic-rich soils; prefers a consistently warm climate typical of lowland rainforests, with filtered light under the forest canopy.

Leaves

• Large and glossy
• Heart-shaped with subtle variegation
• Robust texture

Inflorescence (Spadix & Spathe)

• Brightly colored spathe surrounds a compact spadix
• Not noted for a strong scent

Growth Habit

• Typically, terrestrial
• Grows from a rhizomatous base that allows it to spread gradually in clumps

Light Requirements

• Bright, indirect light
• Direct sun may scorch its leaves

Watering & Humidity

• Regular watering
• Soil evenly moist
• High ambient humidity (around 60% or more) 

Soil & Potting Mix

• A well-draining, organic-rich potting mix that retains moisture without becoming waterlogged
• A mix designed for aroids or epiphytic plants

Temperature & Fertilizer

• Temperature range between 65°F and 80°F
• During the growing season, a balanced, diluted fertilizer applied every 4–6 weeks 

Division and Stem Cuttings

• Propagation is successful through the division of its rhizomes during repotting
• Each division should include a viable growth node

Seeds

• Less common for this species

• Viable seeds require warm, humid conditions for successful germination

Typical Issues

• Spider mites
• Fungal root rot

Treatment Recommendations

• Mild organic insecticide
• Improve drainage
• Adjust watering practice

• Unusual inflorescence
• Resilience in its native tropical habitat
• Often featured in specialized botanical collections and exhibitions

• Rarity and ornamental qualities
• Unique floral display and attractive foliage

Wild Population Status

• Wild populations are limited
• Addressing environmental pressures in its native range

Market Availability
