The black rose, because it symbolizes death and passing away, also indicates a major change or upheaval in the future. In that sense, the black rose also means the death of old habits and the old order. It inspires confidence and enthusiasm by signaling the birth of a new era of hope and joy.
The black rose, tragic in its dark beauty is not always symbolic of unhappiness. The Irish have used the lyrics of "the Little Black rose" during their ongoing battle with the British. Similarly, many anarchist and antiauthoritarian groups have also adopted the black rose as a symbol of mutiny and strength. Therefore, the meaning of the black rose also includes courage and resistance.
Black roses are also good for Halloween, a fitting addition to the decoartions along with black candles, black clothes, and so on.
