The Bigleaf Periwinkle, Vinca major, is also known as Greater (rosy) Periwinkle, Big Perwinkle and Large Periwinkle. The plant is shrub-like and grows to 12" tall with trailing ascending stems; 1-3 feet long. The leaves are dark green and bigger than that of vinca minor. It has solitary violet flowers at the end of the stem. 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 through frost. The leaves are shiny, bright-green and broad with a blunt base with hairy margins. 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 an annual in zones 3-5 otherwise perennial. It can be used on banks or in other rough locations provided soil is suitable. Cut it back hard in the spring to rid plants of discolored foliage and to enjoy new growth.
