Philodendron ‘Ring of Fire’ is one of the most spectacular and sought-after philodendron cultivars, prized for its bold, serrated foliage and striking variegation. A hybrid believed to have originated from a cross involving Philodendron wendlandii and Philodendron tortum, this plant belongs to the Araceae family and has become a true collector’s favourite.

Its leaves are long, narrow, and deeply serrated along the edges, giving them a jagged, almost flame-like appearance. Each leaf can display an extraordinary mix of colours – from deep green and lime to orange, red, cream, and yellow – with the variegation forming streaks, patches, and marbling. No two leaves are alike, making the plant’s overall appearance dynamic and ever-changing.

A relatively slow grower, Philodendron ‘Ring of Fire’ can eventually reach over 1.2–1.5 metres tall as a self-heading plant (not a climber). Its upright, architectural form and fiery leaf palette make it an unforgettable statement piece in any indoor collection.

Philodendron ‘Ring of Fire’ – Care Guide

Light

Requires bright, indirect light to maintain strong variegation. Tolerates medium light, but colours will be less intense and new growth may revert to greener tones. Avoid harsh direct sun, which can scorch the delicate variegated areas.

Watering

Water when the top 3–4 cm of soil feels dry. Keep soil lightly moist during spring and summer but avoid waterlogging, which can cause root rot. Reduce watering in winter when growth slows.

Temperature and Humidity

• Temperature: Thrives in 18–28°C. Protect from draughts and avoid prolonged exposure below 15°C.

• Humidity: High humidity (60–80%) is preferred. Mist regularly, group with other plants, or use a humidifier to prevent brown leaf tips and encourage lush growth.

Soil and Potting

Use a chunky, free-draining aroid mix – peat-free compost blended with orchid bark, perlite, and coco coir. Repot every 1–2 years in spring to refresh the soil and support healthy root development.

Feeding

Feed every 2–3 weeks in spring and summer with a balanced liquid fertiliser, diluted to half strength. Reduce feeding in autumn and stop in winter.

Pruning and Maintenance

Remove old or yellowing leaves at the base to maintain appearance. Being a slow grower, it doesn’t require heavy pruning, but trimming damaged foliage keeps it tidy.

Growth and Maturity

A slow to moderate grower. Over time, Philodendron ‘Ring of Fire’ forms a robust clump with large, serrated leaves up to 45–60 cm long. Its colourful foliage becomes more dramatic as the plant matures.

Common Issues

• Loss of variegation: Insufficient light.

• Yellow leaves: Often due to overwatering or poor drainage.

• Brown edges: Typically linked to low humidity.

• Pests: Occasionally affected by spider mites, thrips, or mealybugs. Inspect leaves regularly.

Background and Benefits

Rare and highly collectable, Philodendron ‘Ring of Fire’ is admired for its kaleidoscope of colours and flame-like leaf form. Each plant is unique, with leaves displaying an unpredictable blend of red, orange, cream, and green. It is a statement philodendron that combines sculptural beauty with vibrant colour, making it one of the most desirable foliage plants in cultivation.
