Philodendron is part of the Araceae family and the native range of this genus is Mexico to Tropical America.
'Caramel Marble' is a hybrid thought to come from a selected sport of Philodendron ‘Pluto’. The leaves of Philodendron 'Caramel Marble' are cordate (heart-shaped) when young, maturing to a deeply lobed and pinnatifid shape. This means the leaves are cut or divided into several deep, finger-like lobes. The leaf margins are entire (smooth) but the overall shape is complex due to the lobing. The lobes themselves can be sinuate (wavy).
New leaves emerge with a reddish-brown hue, as they mature, the colour gradually shifts to be more marbled variegation; this marbling typically features shades of caramel, cream, golden-yellow, and green, and can also include tones of orange, peach, red, and pink. The final color of a leaf is a unique mix of these hues, with no two leaves being identical.
Genus name comes from the Greek ‘philo’ meaning loving and ‘dendro’ meaning tree.
Light: Philodendron 'Caramel Marble' thrives in bright light that is not direct. Strong, direct sunlight can harm its leaves, potentially causing burning or diminishing the vibrant variegation. Insufficient light may result in slower growth and less pronounced, duller patterns. A position near a window with filtered light in a typical UK home is ideal. Variegated forms generally benefit from brighter conditions than their all-green counterparts to maintain their patterns.
Water: The potting mix should be kept consistently damp but not saturated. Allow the upper inch or two of the soil to dry between waterings. Ensure the pot drains exceptionally well to prevent root problems, which can be an issue, especially in the UK's climate. Reduce watering in autumn and winter when the plant's growth naturally slows.
Soil: An airy potting mix that drains well is essential. A mix specifically created for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary air circulation and drainage.
Fertilising: Use a diluted liquid fertiliser every two to four weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 27°C. It should be shielded from cold draughts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: Higher humidity levels are highly beneficial for Philodendron 'Caramel Marble'. Consider using a humidifier or placing the plant on a pebble tray with water to maintain optimal conditions, especially during drier indoor periods in the UK.
Growth Habit: This Philodendron has a vining or climbing growth habit. Providing a sturdy support such as a moss pole or trellis is crucial for encouraging its impressive size and more vigorous vertical development. It will produce aerial roots that attach to these surfaces.
Toxicity: Like other Philodendrons, this plant is toxic if consumed by humans or pets.
