Its leaves tell the story of its origins: glossy, vibrant green blades with an embossed reticulated texture, creating a refined yet bold look. Mature foliage often takes a peltate or semi-peltate form, measuring up to 35 cm long, with slender petioles rising from a compact rhizome. This species doesn’t just blend into your space — it commands attention with quiet elegance, reflecting the lush, cloud-kissed forests it calls home.
