Received this as a pass-along from a neighbor at least 20 years ago. She called it sweet basil. When it first comes up it looks just like your picture,raggins. I let it grow because it is such a beautiful foliage contrast.
Have to remove a lot of it as the summer goes on because it can shade out more desirable bloomers. It self-seeds and I never know from year to year where it will be. I love it. Guess some would call it invasive but it is not that hard to just pull it up when you don't want it.
