Purple flowering shrubs can bring color to your yard all year. The right bush with purple flowers can add a feel of “royalty” to an otherwise tame colored garden space. It can also add a burst of color to an assortment of white flowers, adding a bit more drama to your gardening space.

Finding shrubs with the perfect shade of purple can be challenging, due to the sheer number that are available. Not to mention, you’ll have to consider if it’s hardy to your local climate.
