Holochlamys sp. is a rare and highly sought-after aroid from the rainforests of Papua New Guinea. It is a monotypic genus, meaning it is the only species in its genus, and is closely related to the more common peace lily (Spathiphyllum). Its rarity and unique characteristics make it a prize for serious collectors, especially the variegated forms.

Plant characteristics

Appearance: The plant features oval to lance-shaped leaves with a rich green color and a glossy texture. Unlike peace lilies, its white spathe (the leaf-like bract) is fused and clasps the spadix (the flower spike).
Growth habit: Holochlamys is a perennial that is primarily rheophytic, meaning it grows in or near flowing streams, and can be found in mud or rocky streambeds. For home collectors, this suggests a preference for consistently moist soil.
Flowers: The small, white inflorescence appears below the foliage. After flowering, the structure decays rapidly, unlike the long-lasting flowers of Spathiphyllum.

Care requirements

Mimicking its native rainforest environment is key to a healthy Holochlamys sp.

Light: Prefers bright, indirect light, similar to its peace lily relative. Direct sunlight will likely burn the delicate leaves.
Water: Keep the soil consistently moist but never soggy. Excellent drainage is essential to prevent root rot. Its rheophytic nature means it can tolerate more moisture than other aroids but requires a well-aerated medium.
Soil: Use a very well-draining, moisture-retentive substrate rich in organic material.
Humidity: High humidity (above 70%) is crucial for this tropical plant to thrive.
Container: A pot with good drainage is necessary. Consider placing it in a terrarium or near a humidifier for best results.
