Plants of the genus Nigella are commonly called “devil in a bush” or “love in a mist”, presumably due to their spiky collars. And their seeds are very flavoursome. From wikipedia:
The seeds of N. sativa, known as kalonji, black cumin (though this can also refer to Bunium persicum) onion seed or just nigella, are used as a spice in Indian and Middle Eastern cuisine. The dry roasted nigella seeds flavor curries, vegetables and pulses. The black seeds taste like oregano and have a bitterness to them like mustard-seeds. It can be used as a “pepper” in recipes with pod fruit, vegetables, salads and poultry.
