Plants and Food Color
Date: October 2007
Hi! I had a question about dyeing plants with food coloring.
Why doesnt the stem itself turn the color of the food coloring? Also,
why cant some plants absorb some dye's?
I don't think there is a simple answer because it depends upon what
food dye you select, what plant you select, and other possible factors
such as the pH (acidity or alkalinity) of the "experiment". The
absorption of dyes is a complicated process. The plant itself could
change the color of the dye you "think" you are putting into the plant.
