There can be several things that can cause faded blooms on plants. The most common is that the flowers fade in color as the bloom gets older. But, if your plant started out with faded color, it may be that it is lacking fertilizer or is seeing sunlight much more intense than it is use to. Once in a great while, if a single bloom comes out without color, this is simply a sport or a mutation and is not an issue.
