Flower Color Changes
How do nurseries/florists change flowers to various colors?
For some flowers, the florist can put a dye into the water and the plant
will take it up into the flower stalk.

Hi dear Toni
Not all the flowers easily change colors.
But for some it is easy.
One needs to cut the stalk like a bisel and
put it into a colored solution made with food dyes.
Red and blue color work better.
After some time, about 8-12 hours
the colored solution goes up the stalk and to
the flower and gives it the diferent color.
Of course it must be done withe white flowers.
Thanks for asking NEWTON
