Why Do Tulips Change Color

The most common cause of discoloration in tulips is age. Over time, petals may take on a lighter hue than in previous years and may change color altogether. Since it is a natural process of aging, there is no way to reverse it; if growers want a bolder color for the garden, old plants will be replaced.
