The Heartleaf Philodendron (Philodendron hederaceum), also known as the Sweetheart Plant, is a classic, low-maintenance houseplant loved for its trailing vines and lush, heart-shaped leaves. It’s perfect for beginners and can thrive in various indoor conditions. USDA Hardiness Zone • Grows outdoors in zones 11–12, where it can thrive year-round in tropical or subtropical climates. • Indoors, it can grow in any zone as long as it is protected from frost. Benefits • Air Purification: Filters toxins like formaldehyde and carbon monoxide. • Versatility: Works as a hanging plant, climbing plant, or tabletop display. Characteristics • Appearance: Glossy, deep green, heart-shaped leaves. Variegated varieties may have lighter green or yellow patterns. • Growth Habit: Fast-growing vine that can trail from hanging baskets or climb when supported by a trellis or moss pole. • Size: Indoors, it typically grows 6–10 feet long or more as a trailing plant. Care Requirements 1. Light • Prefers bright, indirect light, but tolerates low light. • Avoid direct sunlight, which can scorch the leaves. 2. Watering • Water when the top 1–2 inches of soil feels dry. • Overwatering can cause root rot; underwatering may lead to drooping leaves, but they usually perk back up after watering. 3. Soil • Use a well-draining, all-purpose potting mix. 4. Humidity • Thrives in moderate to high humidity, but adapts well to typical indoor conditions. • Can benefit from occasional misting or placement near a humidifier. 5. Temperature • Ideal range: 65°F–85°F (18°C–29°C). • Avoid exposing the plant to cold drafts or temperatures below 55°F (13°C). 6. Fertilizer • Feed monthly with a balanced liquid houseplant fertilizer during spring and summer. Reduce feeding in fall and winter
