Is the photo sea kale?
If not sea kale can you tell me what it is and is it edible?

Do NOT under any circumstances go consuming wild kale or its relatives. Many of them will lead you straight to the emergency room. Calcium Oxalate is no joke. This species (unless it is cultivated) contains many seriously toxic members. Unless you planted it as Kale, then don't consume it. As a side note... That does not appear to be Sea Kale. There are too many in this family to give it a proper ID.
