The blue rose is a flower that seeks to convey a message of mystery, enchantment and a sense of the impossible. One should never forget that as a flower that is not found freely in nature, the blue rose has a certain charm and unique mystery that does not reveal itself freely. Much like its mysterious origin, the blue rose means mystery. An appreciation for the enigmatic, the inexplicable is expressed by blue roses. A tantalizing vision that cannot be totally pinned down, a mystery that cannot be fully unraveled is the blue rose. A person who receives the blue rose is the subject of much speculation and thought. A complex personality that does not allow easy interpretation is what the blue rose indicates.

Another meaning of the blue rose is that it symbolizes the impossible, or the unattainable. Since the blue rose itself is a rarity in nature, it stands for something that is hardly within one’s grasp, an object that seems too difficult to be achieved. Thus the blue rose is admired and revered as an unrealizable dream. Source: Roseforlove
