Stenospermation spruceanum Schott

• Genus: Stenospermation
• Botanical Background: Stenospermation spruceanum was first described by botanist Heinrich Wilhelm Schott in the 19th century. Schott’s work in the Araceae family helped lay the foundation for modern aroid taxonomy.

• Geographical Range: Primarily found in the rainforests of South America, particularly in the Amazon and Orinoco River basins, where it grows in the lowland, tropical climates
• Environment: Thrives in humid, shaded environments with consistently warm temperatures and high humidity; typically moist and rich in organic matter, often in the understory of rainforests

Leaves

• Large, glossy, and ovate
• Deep green color
• Leathery texture and prominent venation, adding to their ornamental appeal

Inflorescence (Spadix & Spathe)

• Large, white spathe that envelops a yellowish-green spadix
• Scent is subtle
• May attract pollinators like flies and beetles, which are common pollinators in its native habitat

Growth Habit

• Typically terrestrial but may also grow as an epiphyte in some environments
• Has a rhizomatous growth habit, producing new shoots from its underground rhizomes

Light Requirements

• Prefers bright, indirect light 
• Can tolerate lower light conditions, making it suitable for indoor environments

Watering & Humidity

• Requires consistently moist soil
• Regular watering is essential
• Thrives in high humidity environments and benefits from occasional misting

Soil & Potting Mix

• A well-draining potting mix with a high organic content, such as a blend of peat, perlite, and bark
• Rhizomes need good drainage to prevent rot

Temperature & Fertilizer

• Prefers temperatures between 65°F and 85°F (18°C - 29°C)
• Balanced, water-soluble fertilizer every 4-6 weeks during the growing season helps promote healthy growth

Division

• Division of the rhizomes is the most common method for propagating

Stem Cuttings (if applicable)

• Cuttings of healthy stems with attached roots can also be used

Seeds

• Less common, as it requires specific conditions for germination, including consistent warmth and moisture

Typical Issues

• Aphids, mealybugs, and spider mites
• Root rot can occur if the soil remains too waterlogged

Treatment Recommendations

• Insecticidal soap or neem oil
• For root rot, remove affected areas and re-pot in fresh, well-draining soil

• Plays a role in the understory ecosystem, providing ground cover in humid forests
• Has a distinctive appearance in flower arrangements

• Prized for its bold foliage and attractive inflorescence
• Often sought after by collectors of rare aroids and is a great addition to tropical plant displays

Wild Population Status

• Not currently considered endangered, habitat destruction in the Amazon rainforest poses a threat to its long-term survival in the wild

Market Availability

• Not commonly found in general nurseries
• May be available through specialty aroid retailers or plant collectors
