About Scindapsus Pictus Silver Hero

Scindapsus pictus 'Silver Hero' · also called Silver hero pothos, Silver hero scindapsus · houseplant

Silver Hero is a Scindapsus pictus selection prized for near-fully silver leaves, with a heavier metallic sheen than Exotica or Argyraeus. The matte, heart-shaped foliage trails or climbs slowly. It is more drought-tolerant than true pothos and prefers bright indirect light. Despite the 'pothos' nickname it is a Scindapsus, and like Epipremnum it is toxic to pets.
