Experiment Week #7 Blue plant These are the flowers from the plant I watered with blue food coloring. They’re white |
 |
Experiment Week #7 Magenta Plant These are the flowers from the plant I watered with magenta coloring. They’re white too. |
 |
Experiment Week #7 Roots The coloring did affect the colors of the roots, but not much else. So the answer is that food coloring will not affect the color of white flowers. At least I got to have flowers and they smelled nice. |
It does work with already grown carnations–you can cut them and put them in water with food coloring and as the plants take in the water, they take on the color. Good to know it doesn’t work with all flowers.

Rasinfish it might work with these flowers too, there is a key difference in the two situations. The cut carnations are missing some metobolic processing that the ones with roots get.

Yeah, that too. Makes me wonder how carnations you buy in odd colors at the florist’s shop are colored–before or after they bloom?

After they are cut. No roots => no filters

Well, it has been rather a while since this conversation, but my little sister bought some colored flowers at the store the other day. The ones that were still wrapped up in their buds are white now and the ones that were open are purple, so they definately color them after hey blossom. (Which, had I thought back to my college botany courses I should have known. Plants don’t pump fluids through their circulatory system like we do. It is all based on evaporation at the extremities pulling water up the stems. Since a flower in the bud is shielded from the air, there is no evaporation from the petals and no water goes up into them. On the other hand, the leaves that make up the bud do have exposed stoma and water evaporates from them so we have white flowers and greenish purple bases. (I should so go look up all of the right words for the above bits.
