Vinca major, commonly called greater periwinkle, is a vigorous evergreen trailing perennial widely used as a shade-tolerant groundcover. It forms long, rooting stolons that carpet the soil, with glossy, leathery, ovate leaves 4–9 cm long, often with ciliate margins. In spring and early summer it produces showy, five-lobed, periwinkle-blue to violet flowers 4–5 cm across; sporadic blooms may follow in mild weather. Plants reach 30–50 cm tall, spreading meters over time, suppressing weeds and stabilizing slopes. It thrives in humus-rich, well-drained soils but tolerates a range of textures, pH, and brief drought once established. While valued for erosion control and low-maintenance plantings under trees, V. major can become invasive in favorable climates, especially where winters are mild and shade is abundant, displacing native understory flora. Pruning or edging is often required to confine it. Numerous cultivars exist, including variegated selections prized for brighter shade gardens. Handle with care: all parts contain vinca alkaloids and are toxic if ingested.

How to care for Greater periwinkle
Water
During the first growing season, water weekly to keep the root zone evenly moist. Once established, Vinca major is moderately drought tolerant: water deeply every 10–14 days in prolonged dry spells, allowing the top 2–3 cm of soil to dry between waterings. Avoid chronically soggy conditions, which invite root and stem rot. Container-grown plants dry faster; check the top inch and water thoroughly when dry, then drain excess. Reduce watering in winter.
Light
Best in partial shade to dappled light; morning sun with afternoon shade is ideal. In cool-summer climates it tolerates more sun if soil remains evenly moist. In hot climates, avoid full midday/afternoon sun, which can scorch foliage and reduce vigor. Deep shade is tolerated with lush foliage but fewer flowers. Indoors or on shaded patios, aim for bright, indirect light and adjust irrigation upward with increased light and heat.
Nutrients
Vinca major is not a heavy feeder. In ground, incorporate compost at planting and top-dress each spring with 2–3 cm of compost or apply a balanced, slow-release fertilizer (e.g., 10-10-10) at half label rate. In containers, feed monthly in spring–summer with a dilute balanced liquid (1/4–1/2 strength). Avoid high nitrogen that encourages lanky growth. Do not fertilize in winter or during drought stress; water before and after any application.
Temperature
Hardy in USDA Zones 7–9. Ideal growth occurs in cool to mild conditions (59–75°F / 15–24°C). Established plants tolerate brief heat if shaded and watered, and light freezes in-ground. In colder regions or containers, protect roots from sustained freezes: mulch well and move pots to a sheltered spot when temperatures approach 20°F (−7°C). Extended hard freezes or drying winter winds may scorch foliage, but plants often re-sprout in spring.
