Philodendron cordatum is a popular houseplant native to South America and known for its heart-shaped, vibrant green vining leaves. It thrives in moderate to bright indirect light, requiring well-draining soil and consistent moisture without being waterlogged. This plant prefers high humidity and warm temperatures, making it suitable for indoor environments rather than direct sun exposure. While it’s tolerant of lower light, growth is best with ample indirect light. Philodendron cordatum has air-purifying qualities but is toxic to pets and humans if ingested.. Mature Size: 2-4′ x 2-4′ after 5 years. Shade, Morning Sun Afternoon Shade.
