Anthurium subsignatum Schott

• Genus: Anthurium
• Botanical Background: Described by Heinrich Wilhelm Schott in the mid-19th century, Anthurium subsignatum has intrigued botanists due to its unique foliage and varied forms across its natural habitat.

• Geographical Range: Native to tropical regions of Central and South America, it thrives in areas such as the cloud forests of Ecuador and Colombia.
• Environment: Grows naturally in humid environments with consistently warm temperatures and is often found at elevations where rainfall is frequent. It prefers moist, well-drained soils rich in organic matter.

Leaves

• Large, dark green, and glossy with a slightly undulating margin
• Can grow up to 30 cm long
• Elliptical or ovate in shape
• Prominent central vein

Inflorescence (Spadix & Spathe)

• Spathes are typically green or white, contrasting with the dark foliage
• Spadix is a subtle cream or pale yellow
• Not particularly fragrant

Growth Habit

• Primarily epiphytic but can adapt to terrestrial conditions
• Produces a rhizomatous root system
• Spread and anchor itself to trees or other supports in its native habitat

Light Requirements

• Bright, indirect light
• Can tolerate lower light levels

Watering & Humidity

• Regular watering is necessary to maintain moisture in the soil
• Must be well-drained
• High humidity levels, around 60-80%

Soil & Potting Mix

• A well-draining, moisture-retentive potting mix
• A mix of orchid bark and perlite

Temperature & Fertilizer

• Temperatures range from 20-30°C (68-86°F)
• Fertilize monthly during the growing season
• A balanced, water-soluble fertilizer diluted to half strength

Division and Stem Cuttings

• Division of the rhizomes during repotting
• Ensure each section has at least one healthy growth point

Seeds

• Less common for this species due to the time and effort involved in germinating aroids from seed

Typical Issues

• Aphids, spider mites, and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure that the plant is in well-draining soil
• Avoid letting it sit in water

• Unique leaf texture and shape
• Found in tropical gardens and as an ornamental houseplant

• Striking foliage and relatively easy care
• Less common in cultivation

Wild Population Status

• No immediate conservation concern
• Habitat destruction in some regions may threaten its native range

Market Availability

• Not as widely available as some more common Anthurium species
• Can be found in specialty nurseries or online plant retailers
