This ornamental plant is fast growing. The Greater Periwinkles are an
evergreen, creeping plant with long trailing or arching stems.
The flowers are carried in the short, ascending stems. It flowers from April

It thrives in shady and damp areas; it will
melt in full sun in the southern portion of its range. It is usually sold as
