[Wikipedia] Leaf Description: The leaves have a taco shell shape. When flattened, they have the shape of laurel leaves, with lance-shaped leaf blades up to 10 cm (4") long. The tips of the stems, little stem attaching the leaf to the stems (petiole), the veins of the leaves, and the edges of the leaves, are a glowing reddish color all year long.
