Periwinkle, or Vinca minor, is a resilient, low-maintenance and versatile plant that thrives in both sun or shade. Wherever it is planted, periwinkle will quickly establish itself, filling problem areas under large trees or in darker borders.
As a former professional gardener, I have grown Vinca minor in many different public and private gardens and never found it to be a problem. However, be warned, it does have a vigorous, sprawling habit and can quickly get out of control. Today, it is considered invasive in several states in the eastern United States, so always consult with your local government office before planting.
