I grow Nigella damascena (Love-in-a-Mist) every spring. I guess I should say 'I let it grow every spring.' I planted seeds a few years back and they have re-seeded every year since. The flowers seem, as its name implies, to float in a mist. Once the flower has faded the seed pod looks Dr. Suess-ish! They can be dried and used in dried flower arrangements. I tell everyone they should grow 'Love-in-a-Mist.' Just toss seeds in the fall and that's the only work you'll ever have to do!
