Low-Light Indoor Plant Solution

Harvest Tips

Fun Facts
- 🌱 The 'Sweetheart' cultivar gets its name from its distinctly heart-shaped leaves, which are smaller and more compact than the standard Philodendron hederaceum, making it perfect for tight spaces.
- 🌱 Philodendron hederaceum is often confused with Pothos (Epipremnum aureum), but they differ in leaf shape and stem structure; Pothos has a distinctive node pattern while Philodendrons have smoother stems.
- 🌱 In tropical regions, Philodendron hederaceum naturally grows as a hemi-epiphyte, starting on the forest floor and climbing trees to reach light—this climbing instinct is why it thrives on moss poles and trellises indoors.
