Fun Facts

  • 🌱 Syngonium Red Heart leaves change shape as the plant matures—juvenile leaves are more arrow-shaped while mature leaves become larger and develop more complex lobes, a phenomenon called heterophylly
  • 🌱 The red coloration in the leaves is due to anthocyanin pigments, which also develop more intensely under bright indirect light, making light management crucial for color intensity
  • 🌱 Syngonium is part of the Araceae family and is non-toxic to humans, though it contains calcium oxalate crystals that can cause mild irritation if ingested in large quantities, making it relatively safe around pets compared to more toxic houseplants
