Spathiphyllum mawarinumae G.S.Bunting

• Genus: Spathiphyllum
• Botanical Background: Described by G.S. Bunting, this species is named in honor of an individual who contributed to tropical plant research. Its classification is supported by both classical morphology and modern molecular studies, emphasizing its distinct characteristics within the peace lily group.

• Geographical Range: Native to tropical rainforests in Central and South America
• Environment: Thrives in warm, humid conditions with consistently moist, well-draining soils. The species favors areas with filtered, indirect light, mirroring the light conditions of its native rainforest habitat.

Leaves

• Broad, glossy, and dark green, with an ovate to lanceolate shape and a smooth texture
• Prominent venation that enhances their visual appeal and aids in effective photosynthesis under low-light conditions

Inflorescence (Spadix & Spathe)

• Inflorescence features a slender spadix encased by a pristine white spathe, typically measuring around 8–10 cm in length
• The spathe may emit a subtle fragrance, which serves to attract pollinators
  

Growth Habit

• Terrestrial plant that grows from a rhizome, forming a compact rosette of leaves. Its non-climbing habit and manageable size make it ideal for container cultivation and indoor display

Light Requirements

• Provide bright, indirect light to ensure optimal growth and flowering
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil consistently moist but well-draining to avoid waterlogging and root rot
• High humidity is essential
• Regular misting or using a humidity tray is recommended, especially in drier indoor environments

Soil & Potting Mix

• A well-draining, organic potting mix such as a blend of peat, perlite, and bark is ideal

Temperature & Fertilizer

• Ideal temperatures range from 22°C to 28°C (72°F to 82°F)
• During the growing season, feed with a balanced, diluted liquid fertilizer every 4–6 weeks
• Reduce feeding during the winter

Division

• Propagation is best achieved by dividing the rhizome during repotting
• Each division should include healthy roots and at least one shoot to ensure successful establishment

Seeds

• Propagation is possible but less common due to variable germination rates and a longer maturation period compared to vegetative methods

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering may lead to root rot, and inadequate air circulation can promote fungal infections

Treatment Recommendations

• Control pests with insecticidal soap or neem oil
• Adjust watering practices to ensure proper drainage
• Enhancing air circulation helps prevent fungal issues
  

• Admired for its ability to improve indoor air quality by filtering toxins like formaldehyde and benzene
• Its name honors a contributor to tropical plant research, underscoring its significance in botanical studies

• Enthusiasts prize this species for its striking glossy foliage and elegant white spathe, which add a touch of tropical sophistication to indoor spaces
• Its low-maintenance care and air-purifying properties make it a valuable addition to homes and offices

Wild Population Status

• No immediate conservation concerns
• Habitat loss in tropical regions could impact its natural populations over time

Market Availability

• Moderately available through specialized nurseries and garden centers that focus on tropical houseplants, making it accessible to both novice and experienced collectors
