Calathea 'Lancifolia'
Cultivar: Lancifolia
The Rattlesnake Plant is an ornamental tropical favorite, prized for its striking foliage pattern that mimics the markings of a snake. Its long, slender, lance-shaped leaves emerge from a clumping base and showcase a unique contrast between a light-green top surface with dark green oval blotches and a rich, solid burgundy underside. As a member of the prayer plant family, it exhibits nyctinasty, where leaves fold upward at night. This plant prefers filtered light and humid conditions, making it an ideal choice for interior decor.
The Rattlesnake Plant is a stunning tropical houseplant known for its elongated, wavy leaves featuring bold, dark green spots and deep purple undersides. It thrives in indoor environments with indirect light and consistent humidity.
