Several meanings may be attributed to blue roses, including unrealized dreams, young love, majesty or approval. Significance may also be interpreted based on the context in which a blue rose is given, and may also depend on the particular shade of blue.
Because blue roses do not occur naturally, the color is typically achieved by dyeing them. This has led to an additional significance, that of mystery, being attributed to blue roses as they are considered elusive in origin. A breakthrough in the effort to create a blue rose occurred in 2004, when a Japanese company used genetic engineering. However, the rose created by Suntory is described more accurately as being lavender - a pale shade that contains red hues as well as blue, rather than being a true blue color.
