Rainbow Rose DYI split the stem into several channels and dip each one in a different colored water. This way all the colors will be drawn by the stem into petals and resultant rose will have all the colors in it. The same method can be applied to other flowers especially to Chrysanthemum and Hydrangea. You can use the same idea to color any flower, anyway you like.
"Happy Roses", also known as Rainbow Roses, are the most expensive roses in the world. These are specially treated cream roses that are dyed to brilliant perfection. They make me happy just looking at them!
