  • 🌱 The plant produces aerial roots along its vines that naturally seek out moss poles and surfaces to climb, mimicking its tropical rainforest climbing behavior in nature.
  • 🌱 Mature Sulphur Heart plants can grow 3-6 feet or longer indoors with proper support, making them excellent statement pieces for vertical gardening and living walls.
