After a few days you should clearly be able to see a color change in your flower. In the picture above you can see the top right part is nice and red while the bottom left of our flower in blue. This is the result of different parts of the stem up taking the different colors of water. You can experiment with all sorts of of food colors to make whatever color flower you wish. Below are some of the flowers we made.
