Spathiphyllum cuspidatum Schott

• Genus: Spathiphyllum
• Botanical Background: First described by Schott, this species has been studied for its unique leaf morphology and adaptability to shaded tropical environments. Its classification is supported by both traditional morphological observations and modern molecular analyses.

• Geographical Range: Indigenous to tropical rainforests in Central and South America
• Environment: Thrives in warm, humid climates with rich, well-draining soils. It prefers areas with filtered light under the dense forest canopy and consistent moisture throughout the year.

Leaves

• Dark green, glossy, and have a pointed, or "cuspidate," tip
• They are ovate to lanceolate in shape, medium in size, and display prominent veins that add to their visual appeal

Inflorescence (Spadix & Spathe)

• Produces a classic aroid inflorescence featuring a white spathe that encloses a slender spadix
• Spathe typically measures around 8-10 cm in length and has a subtle fragrance that attracts pollinators

Growth Habit

• Terrestrial, growing from a rhizome that produces a compact rosette of leaves. It does not climb and maintains a manageable size, making it ideal for container growth

Light Requirements

• Provide bright, indirect light for optimal growth
• Direct sunlight may scorch the leaves
• It also tolerates lower light levels, although flowering may be reduced
  

Watering & Humidity

• Maintain evenly moist soil without overwatering
• High humidity is essential
• using a humidity tray or frequent misting can be beneficial in drier indoor settings

Soil & Potting Mix

• A well-draining, organic potting mix, such as one comprising peat, perlite, and pine bark, is ideal
• Ensure the pot has drainage holes to prevent water retention and root rot
  

Temperature & Fertilizer

• Ideal temperatures range from 22°C to 28°C
• Feed with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season, reducing frequency during winter

Division

• Propagation is most commonly done by dividing the rhizomes during repotting
• Each division should have a healthy root system and at least one growing shoot to ensure success

Seeds

• Propagation is possible, it is less frequently used due to variable germination rates and the extended time required for seedlings to mature

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering can lead to root rot, particularly if the soil does not drain well

Treatment Recommendations

• Use organic insecticidal soap or neem oil to control pest infestations
• Ensure proper watering practices and good air circulation to prevent fungal diseases such as root rot

• Admired for its pointed leaf tips, which set it apart from other peace lilies
• Its air-purifying capabilities and ease of care have made it popular in interior landscapes

• Enthusiasts prize this species for its attractive, glossy foliage and elegant white spathe, which bring a tropical aesthetic to indoor environments and offices
• Compact growth habit makes it especially suitable for smaller spaces

Wild Population Status

• Currently no major conservation concerns for Spathiphyllum cuspidatum
• Ongoing deforestation in tropical regions poses a potential risk to its natural habitat

Market Availability

• Widely available in nurseries and garden centers that specialize in tropical houseplants, making it accessible to both amateur and experienced collectors
