Philodendron hederaceum oxycardium 'Variegata', often known as variegated heartleaf philodendron, is a delightful and widely popular vining plant cherished for its heart-shaped leaves adorned with attractive splashes of lighter colour. This Philodendron cultivar features glossy green foliage irregularly marked with creamy white, yellow, or lime green patterns. Its easy-going nature and elegant trailing habit make it a versatile choice for hanging baskets, shelves, or trained on supports in UK homes. It is a member of the Araceae family.
The genus name Philodendron comes from Greek words, reflecting the plant's tendency to grow on trees in its native environment. Hederaceum means "like ivy," referring to its vining habit, and oxycardium means "sharp heart," describing its leaf shape. 'Variegata' indicates the presence of different coloured zones in the leaves.
Light: Philodendron hederaceum oxycardium variegated thrives in bright, indirect light. Strong, direct sunlight can scorch its leaves and cause the variegation to fade, while insufficient light may result in slower growth and less pronounced colour patterns. A position near a window with filtered light in a typical UK home is ideal.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper inch or two of the soil to dry between waterings. Ensure the pot has excellent drainage to prevent root issues, which can be a common problem, especially in the UK's climate.
Soil: An airy and well-draining potting mix is essential. A mix specifically formulated for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary aeration 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 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 shielded from cold drafts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: Average to moderate humidity levels are usually sufficient for this philodendron. While it can tolerate drier indoor air, slightly higher humidity can promote lusher growth.
Growth Habit: This Philodendron has a strong vining or trailing growth habit. It can be allowed to cascade from hanging baskets or shelves, or it can be trained to climb a moss pole or other support for larger leaves.
Toxicity: Like all Philodendrons, this plant is toxic if ingested by humans or pets, as it contains calcium oxalate crystals. Keep it out of reach of children and animals.
