Nigella (Nigella damascena) is a graceful addition to gardens. The threadlike, finely divided leaves give the plants a delicate, airy appearance. Even the flowers are surrounded by the threadlike leaves, giving credence to the "Love-in-a-Mist" moniker. Plants branch out as they grow and top out at about one to one and one-half feet tall. Blue, white, or pink flowers a little more than one inch across adorn the ends of each branch. Following the flowers, curious papery-textured, horned seed capsules are formed.
Nigella is a hardy reseeding annual and is a part of my garden each spring. My acquaintance with it began when a friend brought me a bouquet of it from her garden. My first reaction was, "Wow, will that plant grow and bloom in my garden?" My friend assured me that it would, as it had been growing in her garden for several years. She promised to save me some seed.
True to her word, a few months later Shari brought me a handful of seed pods. I was as smitten with them as I was with the flowers. The papery pods were almost too pretty to shatter for the seeds inside them. I did just that, however.
After clearing the ground of debris and loosening the soil a bit with a rake, I scattered the seeds over the raked area and patted them firmly in place. In late winter, small, feathery seedlings emerged. They remained green and close to the ground and didn't mind the late freezes that came our way. When spring arrived, the stems elongated and before long I was regaled with hundreds of delicate flowers.
My efforts to transplant seedlings to other places in the garden met with disappointment, for they resent disturbance. However, I had much better luck scattering the seeds where I wished them to grow. For best flowering, make sure that you choose a sunny place and keep the soil evenly moist. Don't add fertilizer unless your soil is extremely poor. Rich soil will result in lots of feathery foliage and few flowers.
Several cultivars of Nigella can be found on seed racks and on mail-order or online sources, and several of Dave's Garden members have seeds to share. ‘Miss Jekyl' is a popular cultivar. ‘Persian Jewels' is offered in a mixture of mauve, lavender, purple, and blue. ‘Cambridge Blue' has double flowers and exceptionally long stems that are good for cutting. ‘Blue Midget' is a good front-of-the-border plant. Other cultivars include ‘Albion', Mulberry Rose', ‘Oxford Blue', and others.
A different species, (Nigella sativa) produces black seeds that are the "black fitches" of the Bible. Varying sources call the seeds black cumin, black onion seed, blackseed, black caraway, and nutmeg plant. They are used in the Middle East as a spice, and in Europe as a pepper substitute. Many medicinal uses have been made of blackseed. Nursing mothers use them to increase milk production, and it is believed that they benefit the body's immune system. Various skin conditions are treated with blackseed, and it is reputed to promote digestion and elimination.

Author's revision of some data above: It has come to my attention that Nigella is a hardy annual, and not a biennial, as stated in the original article.
