Observation

The liquid rises through sap tubes (narrow columns) that produce the required capillary force. Capillary action carries water from the beakers to the petals of the white flower causing it to change color. It is the same phenomenon that causes water to move up plants and trees, through the roots, trunk or stem, and then into the flowers and leaves.
