Alternanthera/Ponnanganni leaves are little to medium in size and extended, elliptic, or lanceolate in shape, averaging 3-15 centimeters long and 1-3 centimeters in width. The leaves are dynamic green, lustrous, have smooth edges, and tighten to a point on the non-stem end. The ponnanganni plant is shaggy with little white blossoms and has long, sinewy, stems that spread across the ground and flourish at the hubs. Ponnanganni leaves are fresh and delicate with a nutty, green flavor like spinach.
