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.
