Culcasia glandulosa Hepper

• Genus: Culcasia
• Botanical Background: Culcasia glandulosa was first described by botanist G. Hepper. The genus Culcasia was historically considered part of the larger subfamily Aroideae within Araceae, though there has been some recent reclassification based on molecular data.

• Geographical Range: Tropical regions of West and Central Africa
• Environment: Moist, well-shaded conditions

Leaves

• Glossy, dark green
• Deeply veined
• Ovate to lanceolate in shape, ranging from medium to large size

Inflorescence (Spadix & Spathe)

• Produces a typical aroid inflorescence, spadix surrounded by a spathe
• Spathe is a dull color

Growth Habit

• Grows in clumps
• Does not exhibit climbing behavior or epiphytic traits like some other Araceae species

Light Requirements

• Low to moderate light

Watering & Humidity

• Consistently moist soil
• High humidity levels, typically around 60-80%

Soil & Potting Mix

• Well-draining loamy soil mix enriched with organic matter

Temperature & Fertilizer

• 65–75°F
•  Avoid fertilizing during the winter months when the plant’s growth slows

Division

• Most successfully achieved by dividing the rhizomes during repotting

Stem Cuttings (if applicable)

• Propagated via stem cuttings, though this is less common

Seeds

• Seed propagation is possible but not widely practiced

Typical Issues

• Spider mites, aphids, and mealybugs
• Overwatering can lead to root rot
• Poor air circulation may encourage fungal diseases

Treatment Recommendations

• Insecticidal soap or neem oil
• Infected leaves should be removed
• Root rot should be addressed by improving drainage
• Reducing watering frequency

• Contributing to the biodiversity of tropical rainforest ecosystems

• Utilized in traditional African medicine for various purposes

Wild Population Status

• No specific conservation concerns
• Overall preservation of tropical rainforest habitats is crucial for its survival

Market Availability

• Not widely available in mainstream nurseries, making it a rare find for plant collectors and enthusiasts who are specifically interested in the Araceae family
