Anthurium nanum R.E.Schult.

• Genus: Anthurium
• Botanical Background: Described by American botanist Richard E. Schultes, a specialist in ethnobotany and South American flora, who contributed significantly to the documentation of Colombia’s plant diversity.

• Geographical Range: Endemic to Colombia
• Environment: Grows in humid, shaded environments on forest floors with rich, organic soils, typically at mid-elevations ranging from 1,000 to 1,800 meters.

Leaves

• Small, ovate to cordate leaves, generally less than 10 cm in length, with a smooth, matte surface and a deep green hue
• Petioles are short, adding to the species’ compact habit

Inflorescence (Spadix & Spathe)

• Inflorescence is proportional to the plant’s size, with a slender, upright spadix and a narrow greenish to whitish spathe
• Pollinated by small insects such as gnats

Growth Habit

• Terrestrial species with a clumping growth form
• Grows close to the ground, supported by fibrous roots and a short stem

Light Requirements

• Bright, indirect light
• Avoid exposure to direct sun, which can scorch the small leaves

Watering & Humidity

• Requires regular watering to keep the soil evenly moist
• Prefers humidity levels of 70% or higher to replicate its native montane conditions

Soil & Potting Mix

• Thrives in a loose, well-draining mix such as peat, perlite, and orchid bark
• Moisture retention is important, but avoid compacted soils

Temperature & Fertilizer

• Prefers temperatures between 18–24°C (64–75°F)
• Fertilize once monthly during active growth with a diluted balanced fertilizer

Division

• Propagated by division of basal offsets or stem cuttings containing nodes and roots
• Maintain high humidity to encourage new growth

Seeds

• Propagation is possible but uncommon
• Fresh seeds should be sown in a moist, sterile substrate and kept consistently warm

Typical Issues

• Spider mites, aphids, and mealybugs
• Poor drainage can lead to root rot

Treatment Recommendations

• Use insecticidal soap or neem oil for pest control
• Ensure adequate drainage and avoid overwatering to prevent fungal issues

• Name "nanum" refers to its dwarf size
• Compact habit and modest foliage make it unique among Anthurium species, which are often large and dramatic

• Highly valued in miniature plant collections and terrariums
• Ideal for enthusiasts looking for a true small-scale Anthurium species

Wild Population Status

• Not formally assessed by the IUCN
• Susceptible to habitat degradation

Market Availability

• Rare in cultivation
• Not commonly found in commercial trade
