One meaning of the orange rose is fascination. When you are totally besotted and completely bewitched by somebody, send them an orange rose.
Orange roses carry a tinge of the burning flame in its bosom, and are therefore indicative of the all consuming fire of passion and desire. The beauty and brilliance of the orange rose is simply breath taking. And the Victorians have cleverly used this flame color to indicate the burning heat of passion. The shocking orange color seeks to express an equally intense desire for the loved one. If you have ever wondered how to express your desire without being crude, use the beautiful orange rose.
Enthusiasm and unlimited energy are some other meanings of the orange rose. Again, the symbolism is strengthened by the brilliant hue of the burning flames seen in the orange rose. When new ventures begin, the beginning of a journey – the orange rose celebrates all new beginnings.
The orange rose also indicates pride. When you are honored to be associated with someone, and believe that a person deserves to be lauded, then give him or her some orange roses. "I am so proud of you", the orange rose says.
The orange rose, as brilliant as the blazing evening sky, seeks to convey some equally powerful emotions. Though an open declaration of desire is the most obvious symbolism associated with the orange rose, enthusiasm, pride, best wishes are also some other meanings of the orange rose.
