what is it?

Opheodrys aestivus , commonly known as the rough green snake , is a nonvenomous North American colubrid. It is sometimes called grass snake or green grass snake , but these names are more commonly applied to the smooth green snake ( Opheodrys vernalis ). The European colubrid called grass snake ( Natrix natrix ) is unrelated. The rough green snake is docile, often allowing close approach by humans, and seldom bites. Even when bites occur, they have no venom and are harmless.
