In coastal plains of Alabama it can function as a perennial with a very strong rootstock that cannot be easily pulled from the ground. Two characteristics distinguish arrowleaf and prickly sida: First, the length of the peduncle (flower stalk) to petiole (leaf stalk). Arrowleaf has a longer peduncle and short petiole. Prickly has a short peduncle and long petiole. Second, leaf edges. Arrowleaf has lobed teeth on the upper half of the leaf, while prickly has lobed teethed throughout the leaf margins. |
