Anthurium antioquiense Engl.

• Genus: Anthurium
• Botanical Background: First described by Engler, Anthurium antioquiense has been of interest to botanists studying the vast diversity and ornamental potential of Anthurium species

• Geographical Range: Indigenous to the Antioquia region of Colombia.
• Environment: Thrives in humid, shaded understory conditions with well-drained, organic-rich soils and a consistently warm, moist climate.

Leaves

• Generally large heart-shaped leaves
• Vibrant green tone and subtle patterning

Inflorescence (Spadix & Spathe)

• Bright spathe often displaying shades of red or orange
• Central spadix
• Scent is generally mild

Growth Habit

• Typically terrestrial

• Develops a spreading habit with a robust rhizome system that supports its growth in dense forest understories

Light Requirements

• Bright, indirect light, mirroring the dappled sunlight found in its native forest habitat

Watering & Humidity

• Regular watering is essential to maintain moist soil conditions
• High humidity is critical, though care must be taken to avoid waterlogging

Soil & Potting Mix

• A rich, well-aerated mix that includes organic matter—such as a peat-based blend with perlite—is ideal for promoting healthy root development

Temperature & Fertilizer

• Optimal temperature range is between 65°F and 80°F

• Balanced, liquid fertilizer applied during the growing season helps support vigorous growth

Division and Cuttings

• Most common propagation technique is dividing the rhizomes

• Stem or node cuttings can also be successful, although division tends to yield more consistent results

Seeds

• Less favored due to slow germination rates and variability in the offspring

Typical Issues

• Spider mites or mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Ensuring good air circulation
• Using organic insecticides or mild fungicides are effective measures for keeping pests and diseases at bay

• Collectors value this species for its rarity and unique adaptability to indoor cultivation

• Presence adds a touch of exotic flair to any plant collection

• Distinctive foliage and ornamental spathe make it a coveted specimen for both botanical enthusiasts and collectors, appreciated for its natural beauty and cultural significance

Wild Population Status

• Not currently listed as endangered

• Ongoing conservation efforts continue to monitor its status

Market Availability

• Relatively rare in cultivation

• Primarily available through specialized plant collectors and botanical institutions
