Purple perennials are very popular, based on the high number of searches for plants with purple flowers.
One of the easiest coordinated garden color scheme is purple perennial flowers combined with touches of white and blue.
Your choices of flowers in these colors are nearly endless with so many purple spring and summer blooming flowers to choose from.
So creating a beautiful flower bed using these calming colors is a snap.
Purple, white and blue are forgiving colors, unlike reds for example, all tints and shades of these colors work so well together.
It’s nearly impossible to create a mix of these three hues that clash with each other.
