• Genus: Spathiphyllum
• Botanical Background: Described by Diaz Jimenez and Pérez-Farrera, this species is part of the ongoing research on Spathiphyllum diversity. Its classification has been supported by both traditional morphological studies and modern molecular analyses.

• Geographical Range: Native to the tropical rainforests of Central America
• Environment: Thrives in warm, humid conditions with consistently moist, well-draining soils. The species typically grows in the shaded understory of rainforests, where it receives filtered light and high humidity.

Leaves

• Dark green, glossy, and ovate to lanceolate, with a smooth texture and prominent veining
• Their size and shine add to the plant's overall decorative appeal
  

Inflorescence (Spadix & Spathe)

• Inflorescence consists of a slender spadix enclosed by a white spathe that can reach up to 10 cm in length
• Spathe has a mild fragrance that attracts pollinators, mainly small insects

Growth Habit

• Terrestrial plant that grows from a rhizome. It forms a compact rosette of leaves, making it well suited for container cultivation and indoor environments

Light Requirements

• Provide bright, indirect light for optimal growth
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil evenly moist but ensure proper drainage to avoid waterlogging
• High humidity is essential
• Misting or using a humidity tray can help maintain the necessary moisture

Soil & Potting Mix

• A well-draining, peat-based potting mix enriched with perlite or orchid bark is ideal for this species

Temperature & Fertilizer

• Ideal temperatures range from 22°C to 28°C (72°F to 82°F)
• Feed with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season

Division

• Propagation is best achieved through rhizome division
• Carefully separate sections of the rhizome during repotting
• Ensuring each division has healthy roots and at least one shoot

Seeds

• Propagation is possible but less commonly used due to slower growth and variable germination rates

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering can lead to root rot; therefore, maintaining proper drainage is key

Treatment Recommendations

• Use insecticidal soap or neem oil to treat pest infestations
• For fungal issues, improve air circulation and reduce watering frequency to prevent root rot

• Known for its ability to improve indoor air quality by filtering toxins such as formaldehyde and benzene
• A subject of interest in studies on tropical plant diversity

• Enthusiasts prize this species for its elegant white spathe, glossy dark green leaves
• Compact growth habit, which make it ideal for indoor decoration and office environments

Wild Population Status

• No significant conservation concerns for Spathiphyllum croatii at present
• Habitat loss in tropical rainforests remains a general threat

Market Availability

• Moderately available through specialized nurseries and plant collections, and is widely appreciated by collectors of tropical houseplants
