No, no, no - not Nigella Lawson! Actually there is a culinary connection and I'll deal with that shortly.
I am referring to Love-in-a-mist, Nigella damascena. This pretty blue-flowered (occasionally pink)annual was present in our front garden when we moved here some three years ago. Every spring I pull out dozens of seedlings; every year more appear. I don't mind as long as they don't get out of hand.
