About this plant
Vinca major, commonly called greater periwinkle, is a fast-growing evergreen groundcover with shiny, dark green leaves and attractive violet-blue flowers. It is often used to cover large areas, prevent soil erosion, and add color to shady spots. The plant spreads by trailing stems that root at nodes, making it effective for ground coverage but also potentially invasive in some regions.

Watering. Water regularly during the growing season but allow the soil to dry out between waterings. Reduce watering in winter. Avoid overwatering to prevent root rot.
Fertilizing. Feed Vinca major once in early spring with a balanced, slow-release fertilizer to support growth. Additional feeding is usually not necessary unless the soil is very poor.
Vinca major is a tough, low-maintenance groundcover that grows well in shade or partial sun. It prefers well-draining soil and can tolerate dry conditions once established. Watch for overwatering, which can cause root rot. Prune occasionally to control spread and keep it tidy.

Toxicity & Safety
- Toxic to humans
- Mildly toxic
- Toxic to pets
- Mildly toxic
- Weed potential
- Potentially invasive
The plant is mildly toxic if ingested and can cause stomach upset. Keep away from children and pets who might chew on it.
Allergy information
- Allergy risk
- Low
- Allergy triggers
- Sap or latex, Skin contact
- Pollen level
- Low
Vinca major can cause mild skin irritation in some people who touch its sap. It produces little airborne pollen, so it is unlikely to cause typical pollen allergies. To avoid skin irritation, wear gloves when handling or pruning the plant.
Common problems
Overwatering can lead to root rot. In very wet or poorly drained soil, the plant may suffer from fungal diseases. It can become invasive if not controlled, spreading aggressively in some areas.
Uses
Used as an ornamental groundcover in gardens and landscapes, especially for erosion control on slopes and shady areas. Its attractive flowers add color to shaded spots.
Notes
Prune regularly to keep growth in check and prevent it from overtaking other plants. It can be grown indoors in bright indirect light but thrives best outdoors. Avoid waterlogged soil to prevent root problems.
