White has ever been a symbol of innocence, of a world unspoiled and untarnished. The meaning of a bunch of glowing white roses is innocence and spiritual love. The white rose glorifies a love that is unaware of the temptations of the flesh and resides only in the soul.
Sometimes called “the flower of light”, one of the meanings of white roses is everlasting love – love stronger than death, an eternal love, undying and all sustaining. White rose speaks of a love that is sustained more by loyalty, reverence and humility than by red-blooded passion. So, in its capacity to worship someone till death, the meaning of a white rose is unchanging loyalty that endures beyond all else.
The meaning of shimmering white roses is not very hard to decipher if you go by their appearance. The color white has always been synonymous with purity and virtue. And so, sincerity, purity, and chastity are some of the obvious meanings of a white rose. When you need to convince that your affections are straight from the heart and are as pure as virgin snow, use a white rose.
