How to Make White Carnations Change Into Different Colors

With a little work, you can produce carnations in colors nature never considered.

Whether you are teaching students about capillary action or designing a floral arrangement, changing the color of white carnations is a simple, engaging project. It requires no special equipment or skills, other than a little patience and some time.

Things You'll Need

• Jar or vase
• Food coloring
• White carnations, with stems

Instructions

1. Fill a jar with water and add food coloring. Mix well. The more food coloring you use, the darker the petals will become. Begin with about 1/4 teaspoon to 1 cup of water and adjust it to your personal preference.

2. Cut the ends of the stems at an angle, as this creates a greater vein surface area. Use a sharp knife to avoid crushing the capillary veins.

3. Remove any leaves that would otherwise be underwater, so that the flowers will stay attractive longer.

4. Place the stems in the colored water. Let them sit until the petals draw up the color --- usually several hours, or overnight.

Tips & Warnings

• Maintain the color by replacing old water with freshly colored water every other day.

• Give your dyed carnations a little extra "bling" with a little dusting of florists' glitter. Arrange them with greenery and beaded floral picks.

• Food coloring may discolor plastic containers.
