HOW YOU CAN CHANGE THE COLORING OF CUT FLOWERS
To change white carnation-type petals to green, stand the long-
stemmed flowers in water containing a green aniline dye. Other
suitable aniline dyes may be used to achieve colored stripes on
white flowers.
Place flowers over a basin of water which contains a very small
amount of ammonia in a bell glass.
The petals will usually change. For example, many violet-colored
petals will change to green; red colors will become green, white will
turn yellow and dark carmine will turn black.
Violet-colored asters can be moistened with a very mild solution of
nitric acid. The ray florets will turn red and will also acquire a
pleasant scent.
