I bought some white gerbera daisies yesterday so that I could try to dye them different colors. So far, my experiment has not worked. After nearly 36 hours, the flowers are still white! What I did discover is that when sunlight hits the glass vases, the shadow is the same color as the colored water.
White carnations is what you need! I don't think it will work with these...but maybe if you leave them for a long time the green will soak up. Nice picture all the same!
