Have you ever seen green daisies or carnations during St. Patrick’s Day or Easter?
I can tell you as the granddaughter of a florist, they don’t grow that way naturally.
I can also tell you, you can easily color your own, so don’t pay the extra $3 for green flowers. Just buy the white ones and enjoy a simple science experiment at home!
This activity will encourage your Lil’ to ask questions about plants and how they grow and it is an opportunity for them to engage in science experiments in a meaningful way.

Lil’ Explorers Focus Skills


  • Pose “what” and “why” questions about their surroundings
  • Make predictions and perform experiments
  • Understand 3 of the 5 senses to make observations

Visual Arts

  • Identify basic colors

Lil’ Creators Focus Skills


  • Pose “what,” “why” and “how” questions about their surroundings
  • Make predictions, perform experiments, and discuss results
  • Use 5-senses to make observations

Visual Arts

  • Identify basic colors and understand that you can combine colors to make new colors

Required Materials

Fresh White Flowers

*Clear Cup


*Food Coloring


Step #1
Fill a clear cup or vase 3/4 of the way with water.

  • We chose to do 6 cups so that we could experiment with different colors.
Step #2
Add food coloring to the water.
This is a great opportunity to work on mixing colors.
  • Blue + Red = Purple
  • Red + Yellow = Orange
  • Yellow + Blue = Green
Step #3
Cut/trim the stems of the flowers.

*This is a CRUCIAL step. Plant stems are like skin, they seal up like a scab when they are picked so in order for them to absorb new water, you need to reopen their flesh (stem) by cutting them.

Step #4
Place your flowers in the colored water and wait overnight to see their change.
Step #5
Talk with your Lil’ about what they think will happen.

  • Encourage them to make predictions
  • Invite them to tell their other parent or their sibling what they did as verbalizing their actions reinforces their comprehension.
Step #6
The next day, observe your flowers and talk about the results.

Ask your Lil’ why they think the flowers changed colors.

Conversations about the experiment are equally as important as the experiment themselves.

Teacher Tip

In this experiment, the cells in the stems absorb the colored water and carry it to the white petals. When the white petals drink (absorb) the colored water, their petals change colors just like when your tongue changes color because of the food and drinks you eat.
