What is the meaning behind Black Bacarra roses?

There are two contradictory meanings behind Black Bacarra roses, which are not solid black but a deep crimson color with blackish edges. Some think these flowers represent hope and positivity due to the fact that black roses don't actually exist.

The Victorians thought that these blooms represented fatality, fascination or farewell. They believed in floriography, the language of flowers, and they used it to express feelings or communicate thoughts without talking. They gifted small "talking bouquets" called nosegays to each other and wore them as fashion accessories. The Victorian practice of floriography was inspired by 18th-century Turkey, in which tulips were an obsession.
