Philodendron ‘Red Sun’ is a vibrant and compact tropical houseplant, prized for its fiery new growth and rich, glossy foliage. A hybrid from the Araceae family, this self-heading Philodendron (meaning it grows upright rather than trailing) is admired for its brilliant red and bronze tones, which gradually deepen to lush green as the leaves mature.

Each leaf emerges a bright sunset red, transforming into shades of copper, burgundy, and eventually glossy dark green. The strong, upright stems are thick and fleshy, giving the plant a bold, sculptural appearance. Compact and easy to care for, ‘Red Sun’ adds instant colour, warmth, and tropical energy to modern interiors — a perfect choice for desks, shelves, or as a vibrant floor plant in smaller spaces.

Resilient and fast-growing, this hybrid is as easy to care for as it is striking, making it an excellent addition for collectors or beginners looking to add a splash of tropical colour to their home.

Philodendron ‘Red Sun’ – Care Guide

Light

Thrives in bright, indirect light. The vibrant red and bronze hues are most vivid in good light, though the plant will tolerate moderate levels. Avoid strong, direct sunlight, which may scorch the delicate new leaves.

Watering

Water when the top 2–3 cm of soil feels dry. Keep the soil lightly moist but not soggy. Allow excess water to drain freely and reduce watering slightly in winter. Overwatering can lead to root rot.

Temperature and Humidity

• Temperature: Prefers warmth, ideally 18–28°C. Protect from draughts and cold temperatures below 15°C.

• Humidity: Enjoys moderate to high humidity (50–70%). Mist occasionally or place near a humidifier to keep leaves glossy and prevent brown tips.

Soil and Potting

Use a chunky, well-draining aroid mix – a blend of peat-free compost, orchid bark, perlite, and coco coir works best. Repot every 1–2 years in spring to refresh the mix and promote strong root development.

Feeding

Feed every 4–6 weeks in spring and summer with a balanced liquid fertiliser to encourage steady growth and vibrant leaf colour. Avoid overfeeding, especially in winter.

Pruning and Maintenance

Remove any yellow or damaged leaves to maintain a tidy appearance. Wipe leaves regularly with a soft, damp cloth to keep them free from dust and enhance their natural sheen.

Growth and Maturity

A moderate to fast-growing self-heading Philodendron, typically reaching 40–60 cm tall and wide indoors. With age, it forms a dense clump of upright stems and colourful leaves.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Dull colouration: Insufficient light.

• Brown leaf tips: Low humidity or inconsistent watering.

• Pests: Occasionally mealybugs, thrips, or spider mites — inspect and clean leaves regularly.
