Philodendron 'Red Sun' is the self-heading Philodendron that makes new leaf day feel like a weather event—those broad, glossy leaves emerge in vivid copper-red to burnt orange before cycling through warm amber and finally settling into deep, rich green with a warm undertone that holds just enough of the sunrise it started as. She builds into a full, lush architectural specimen without needing a climbing support, pushing those warm-toned new leaves with enough regularity that the copper glow is always represented somewhere on the plant. Bold, warm, and entirely self-sufficient about commanding a room.
Care Card
🌿 Light — Bright indirect preferred. That vivid copper-red new growth develops its most saturated color with good light; low light causes new leaves to emerge paler and the warm color journey loses the drama that makes this cultivar worth having.
💧 Water — Let the top 1–2 inches dry between waterings, then water thoroughly and drain. Standard Philodendron drought tolerance applies; well-draining aroid mix keeps roots healthy and those warm-toned leaves cycling through their full color range on schedule.
💨 Humidity — 50–70% preferred. More tolerant of average humidity than collector aroids; a humidifier supports the best new leaf color and keeps mature leaves looking rich and glossy.
🌡️ Temperature — 65–85°F. Never below 60°F. Stable warmth keeps those copper new leaves unfurling consistently; cold drafts reduce the warm color intensity that makes the Red Sun worth having.
🌱 Fertilizer — Half-strength balanced liquid every 2–3 weeks in spring and summer. Monthly in early fall. Nothing in winter; consistent feeding supports the new leaf production and warm color expression that is the whole point.
⚠️ Toxicity — Toxic to pets and humans. Calcium oxalate crystals cause oral irritation and vomiting if ingested.
🐣 Beginner Friendly? — Getting there. Standard Philodendron care with a dramatically more colorful and warm payoff—a great choice for intermediate growers ready for something that makes new leaf day feel like an occasion.
