I was thinking of coming up with something unique to give my wife on Valentine’s Day.
Unfortunately, those rainbow-colored roses don’t really occur in nature. The original “Rainbow Rose” has the seven colors – red, orange, yellow, green, blue, indigo, and violet – of a rainbow, and is made by splitting the rose’s stem and dipping each split into different coloured water. The stems draw up the water into the flower petals resulting in a multi-colored rose. Incidentally, other flowers like chrysanthemum and hydrangea can also be made into “rainbow” variants.
If you want to give her something different this Valentine’s Day, I suggest you skip the roses, rainbow or not. Other blooms like tulips, orchids, daisies, and sunflowers can be just as romantic. You can surprise her with a beautiful bouquet of flowers delivered by online florists like this one, to show how much you care no matter how busy you two are.
