Greater Periwinkle Plant Care

Greater Periwinkle (Vinca major) belongs to the Apocynaceae family within the Vinca genus. Greater Periwinkle is native to the western Mediterranean. Greater Periwinkle is also known as Big Periwinkle, Blue Periwinkle, Large Periwinkle.

Greater Periwinkle displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 2 ft. Greater Periwinkle produces small, colorful, trumpet-shaped flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Greater Periwinkle every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Greater Periwinkle thrives in full sun to partial shade.

Vinca major tolerates temperatures of 60–80°F. Greater Periwinkle prefers humidity levels of 40–60%.

Well-draining, fertile soil with added compost or organic matter. Good drainage is essential for Greater Periwinkle to prevent waterlogging, which leads to root rot and fungal issues.

Feed Greater Periwinkle every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining, fertile soil with added compost or organic matter. Avoid low spots where water collects after rain.

Greater Periwinkle is suited to USDA Zone 7a – 9b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Greater Periwinkle can spread to about 2 ft (0.6 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Greater Periwinkle while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Greater Periwinkle is hardy down to USDA zone 7a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Greater Periwinkle can be propagated through stem cuttings, division. Similar propagation techniques also apply to lesser periwinkle plant care, which shares the same genus.

Greater Periwinkle is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Greater Periwinkle grows outdoors in USDA Zone 7a – 9b. It survives winters down to planting zone 7a. Greater Periwinkle is native to the western Mediterranean.
