|Here is a quick capture of a red tulip that was tucked behind a large stone in the garden at Nathan Phillips Square. This tulip was the only one in the bed that was opened and posing for the camera. It had vivid bright red petals and was rich in anthocyanin. Anythocyanin is a pigment that exists only in leaf cells and is responsible for the red skin of apples, the purple of grapes and the multitude of colours in the fall. If the sap's acid level is high, the petals would appear red and if it is neutral, they would have more of a blue colour.
