Vinca major, commonly known as greater periwinkle, is a perennial plant from the Apocynaceae family. Native to Europe and western Asia, it has been introduced and naturalized in many parts of the world. This plant features glossy, dark green, oval-shaped leaves that grow opposite each other on the stem. It produces beautiful blue-violet flowers with five petals, which bloom from spring to fall.
Vinca major is a popular ground cover due to its ability to spread quickly and form dense mats of foliage. While it can grow up to 12 inches tall, it may spread up to 6 feet wide under ideal conditions. The plant thrives in moist, well-drained soil with partial shade or full sun exposure.
The leaves of Vinca major contain alkaloids that have been used for centuries in medicinal treatments for conditions such as high blood pressure, diabetes, and cancer.
It's important to note, however, that Vinca major can become invasive in areas where it has been introduced. It competes with native plants for resources, potentially disrupting ecosystems. Therefore, it should be planted responsibly or avoided entirely if there is a concern about invasive species in your area.
Overall, Vinca major is an attractive ground cover option, thanks to its beautiful flowers and glossy foliage. However, care should be taken when planting this species outside its native range to prevent ecological damage or disruption in local ecosystems. Gardeners should manage this plant properly over time to avoid invasiveness and consider less aggressive alternatives when appropriate.
Bigleaf periwinkle belongs to the Vinca genus, commonly known as periwinkles. To differentiate the plants within this genus, each species is given a name that highlights its unique characteristics. Like many Vinca plants, the flowers of the bigleaf periwinkle feature five petals arranged in a shape reminiscent of a windmill. However, what truly sets this plant apart is its leaves. Compared to other Vinca species, the leaves of the bigleaf periwinkle are larger, reaching sizes of 2 to 9 centimeters. The species name "major," which means "larger" or "greater," aptly describes this defining trait and thus gives the plant its common name, bigleaf periwinkle.
Greater periwinkle is generally resistant to disease and is usually not susceptible to illnesses. However, it can be prone to leaf spots when light and ventilation are poor and watering is excessive.

Fertilizer
Typically, a single fertilizer application in spring is enough for Greater periwinkle, although repeated feedings can enhance growth. Apply every month to every month and a half. Fertilizing improves leaf appearance and function, helping maintain uniform color and a healthy texture. It also promotes root development and nutrient uptake for sustained plant health.
Pruning
The greater periwinkle is a resilient evergreen plant that produces beautiful blue-purple flowers. To promote healthy growth and vibrant blooms, it's best to prune the plant from early to late spring. Be sure to trim overgrown stems and remove any dead foliage to prevent disease. Regular maintenance helps keep the plant from becoming invasive and ensures it retains a neat shape.
Pot & Repot
Repot Greater periwinkle in early spring, selecting a container only slightly larger than the current one and with proper drainage. Use a well-draining potting mix, making sure the root ball is positioned at the same level as before. Gently tease out any root-bound roots. After repotting, water thoroughly and place the plant in a warm, shady spot. Regular pruning helps keep the plant’s size in check and encourages new growth.
