Question

How do you artificially colour a live flower which has its' own natural colour ?

Answer 1

You can clip the bottom of the stem and put it in water with a water soluble dye. This works if the flower has a light color.

In florists, they are colored by a spray-on additive.

Some flowers are effected b the acidity or alkalinity of the soil and can change between a red, purple and blue.

Answer 2

You put it in water that has a lot of dye in it.
