Vinca minor - lesser periwinkle
Lesser periwinkle is a delicate dwarf shrub but once it has gained a footing it doesn’t easily relinquish it. It is a good choice if a ground-cover plant is needed in areas which are very shady. At Mustila, it is one of the basic plants in the Rhododendron Valley. It gradually forms a tight mat when its long creeping tendrils root themselves from their joints, and produce erect short stems. The evergreen leaves are small and stiff, growing opposite on the erect short stems.
