Periwinkles are also known by the name of Vinca or Vinca Vine. They have been around for hundreds of years and are best known as a ground cover because of their hardiness and ability to grow in many different soils and in both shade and sun. They are generally drought tolerant. They make a good bedding plant.
In some places, periwinkles have become invasive and have taken over woodland area, causing their banishment.
White and deep rose colors add variety to the landscape.
I especially like this color of Periwinkle, the pale pink.
