Anthurium papillilaminum is a rare and highly sought-after aroid, prized for its large, velvety, heart-shaped leaves that typically display a deep olive-green hue. The foliage has a leathery texture and a subtle, soft sheen, with veins that are usually not prominently lighter than the leaf blade itself. This slow-growing species maintains a manageable size, making it a highly desirable addition to indoor collections in the UK. It is a member of the Araceae family.
The genus name Anthurium comes from Greek words, indicating a distinction from the flower's tail-like part and the modified leaf surrounding it. Papillilaminum refers to the characteristic tiny, nipple-like bumps (papillae) on the leaf surface.
Light: Anthurium papillilaminum thrives in bright, indirect light. Strong, direct sunlight can damage the leaves, while insufficient light can lead to slower growth and less vibrant coloration. A spot near a window with filtered light in a typical UK home would be suitable.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper inch or two of the potting mix to dry slightly between waterings. Ensure good drainage to prevent root issues, which can be a common problem, especially in the UK's climate.
Soil: A potting mix that drains exceptionally well and is airy is essential. A mix specifically designed for aroids, incorporating materials such as perlite, orchid bark, and sphagnum moss, is often recommended to provide the necessary aeration and drainage.
Fertilising: Use a diluted, balanced liquid fertiliser to feed the plant every four to six weeks during its active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months when the plant's growth naturally slows.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 27°C (65°F and 80°F). It should be protected from cold drafts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: High humidity levels are highly beneficial for Anthurium papillilaminum, ideally above 60%. Consider using a humidifier, pebble tray, or placing it in a naturally humid environment (like a bathroom) to maintain optimal conditions, especially during drier indoor periods in the UK.
Growth Habit: This Anthurium is typically terrestrial in its natural habitat, growing on the forest floor, but can also be hemiepiphytic. It usually exhibits a compact, upright growth habit, with new leaves emerging from a central stem.
Toxicity: Like other Anthuriums, Anthurium papillilaminum is toxic if ingested by humans or pets, as it contains calcium oxalate crystals. Keep it out of reach of children and animals. Its sap can also be irritating to the skin.
