Language of flowers:
Nigella (or Love-in-a-mist) - "You puzzle me."
Love-in-a-mist (Nigella damascena) is one of my favorites.
Love-in-a-mist gets its evocative name from the way a tangle of ferny, fennel like foliage form a mist around the flowers. However, obviously not everyone felt about it in the same way, as it was also known as devil-in-a-bush and Jack-in-prison (???). Because of its misty foliage like a veil of secrecy, the flower is a symbol of perplexity. In some regions in Europe, women used to give Nigella as a refusal to their undesirable suitors, since the flower is also a symbol of unrequited love.
