Common periwinkle (Vinca minor)
Vinca minor, or Common periwinkle, provides attractive evergreen ground cover with lavender-blue flowers across USDA Zones 4-8.
Complete Plant Information
Overview
Vinca minor, widely recognized as Common periwinkle, stands out as one of the most trusted and utilized evergreen ground covers available for landscaping today. Its dense, trailing stems, adorned with smooth, dark green leaves, root readily at the nodes, creating a rapid and attractive mat that suppresses weeds effectively. This vigorous habit is what makes Vinca minor invaluable for covering large or difficult spaces.
The plant offers visual interest nearly year-round, punctuated by charming, tubular, lavender-blue flowers that appear primarily from May into June, often continuing intermittently into the fall. Ideal for brightening shady garden corners, Common periwinkle provides texture and low-growing color where many other ground covers fail due to lack of light.
Gardeners value this species for its hardiness and adaptability, allowing it to thrive, forming a living blanket that stabilizes slopes. Whether you seek dependable performance under mature trees or basic erosion control, Vinca minor delivers consistent, robust coverage.

How to Grow
Planting Vinca minor is best done in the spring or fall, allowing the roots time to establish before extreme summer heat or deep winter freezes arrive. This plant is remarkably flexible regarding soil, thriving in average, well-drained conditions, but it performs best in moist, humusy soils enriched with organic matter when placed in partial shade. For a quick, dense cover, space individual plants about 8 inches apart; for broader areas where patience is an asset, spacing up to 12-18 inches is sufficient, as the vines will fill in quickly.
Care requirements are generally low once established, aligning with its “Dry to medium” water needs. While it tolerates drought once rooted, occasional watering during prolonged dry spells will keep the foliage lush. Common periwinkle rarely requires fertilization; natural soil fertility is usually adequate, especially if planting in humus-rich soil. Pruning is only necessary if the plant begins to encroach too far into unwanted areas or if it needs revitalization after severe winter dieback; simply trim back the stems as needed in early spring.
One special note concerns its tolerance for heavy shade—while it manages close to full shade, be aware that bloom production lessens considerably in deep darkness. Provide standard protection for the roots and foliage during very cold winters in the lower Hardy Zones (4), although its evergreen nature usually provides sufficient self-insulation.
Landscape Uses
The primary role of Vinca minor in the landscape is as a versatile, fast-spreading ground cover, particularly effective underneath large trees or in neglected, shady borders where lawn grasses fail. Its vigorous, rooting stems make it an excellent candidate for stabilizing steep banks and slopes, mitigating soil erosion reliably throughout the year.
This plant is also frequently utilized beneath established shrubs or as a neat border around informal beds, offering substantial year-round green. Furthermore, it excels at blanketing the ground beneath spring-flowering bulbs; the dense foliage of Vinca minor hides the unsightly dying foliage of bulbs like daffodils and tulips as they complete their seasonal cycle.
Designers often pair the evergreen texture of Common periwinkle with contrasting textures, such as ferns or hostas, which appreciate similar partial shade conditions. Its low profile ensures clear sightlines, making it a functional backdrop rather than an imposing foreground element.

Noteworthy Characteristics
Vinca minor commonly known as vinca or periwinkle is one of the most popular and widely used ground covers. Trailing stems with smooth, evergreen leaves (to 1.5” long) root at the nodes as they go along the ground and quickly spread to form an attractive ground cover. The genus name refers to the Latin word for “to bind or wind around,” referencing the flexible stems once used in making wreaths.

Potential Problems
While Vinca minor is celebrated for its resilience, gardeners should monitor for vinca stem canker, a fungal blight that can sometimes damage or kill large, established patches, especially under overly wet conditions. Applying a fungicide specific for blight early in the season may help prevent outbreaks in susceptible areas.
The most common actual “problem” associated with this plant is its vigorous spreading habit. Common periwinkle can spread aggressively beyond its intended boundaries, potentially creeping into adjacent lawns or manicured garden areas. To manage this assertiveness, install physical barriers like edging or perform routine summer trimming to keep the growth contained where desired.
Frequently Asked Questions
What hardiness zones is Common periwinkle suitable for?
Common periwinkle (Vinca minor) is reliably hardy across USDA Zones 4 through 8.
How large does Vinca minor grow?
This herbaceous perennial typically reaches a height between 0.25 and 0.5 feet, spreading horizontally from 0.5 to 1.5 feet wide.
What sun exposure does Vinca minor need?
Vinca minor prefers full sun to part shade locations but is notably tolerant of heavy shade conditions, though flowering will be reduced there.
When does Common periwinkle bloom?
Common periwinkle usually puts on its main display of lavender-blue flowers between May and June.
Conclusion
The reliability and evergreen nature of Vinca minor secure its place as a top-tier residential and commercial ground cover, offering dependable coverage, erosion control, and sporadic blooms. For gardeners seeking to conquer shady slopes or provide year-round greenery, Common periwinkle remains a stellar choice. Before planting, confirm your site falls within USDA Zones 4-8 and ensure the soil has adequate drainage for long-term success.
Companion Planting
When using Vinca minor as a ground cover, pairing it with plants that share similar moisture and light requirements creates a harmonious woodland or shade garden scheme. Excellent companions include various Hostas, whose bold foliage offers a textural contrast to the fine, glossy leaves of the periwinkle. Similarly, spring ephemerals like Trillium or native woodland phlox can enjoy the dappled light before the Vinca minor fully blankets the area.
For areas receiving slightly more light (part shade), consider pairing this vigorous spreader with ferns that prefer dry soil, such as Christmas Fern (Polystichum acrostichoides). This combination provides layering, with the taller ferns offering vertical accents above the low-mounding, trailing habit of the Common periwinkle.
Propagation Tips
Propagating Vinca minor is incredibly easy due to its natural rooting habit. The most common method is through stem cuttings taken anytime during the active growing season. Simply take trailing stems that have roots at the nodes—or cut sections that are 4 to 6 inches long—and bury the nodes slightly beneath the soil surface in a desired new location.
Because the Vinca minor stems naturally root wherever they touch moist soil, division is also highly effective. In early spring or early fall, carefully dig up established clumps and gently divide them into smaller sections, ensuring each division has a healthy length of stem and several roots attached. These new divisions can be immediately planted where additional coverage is needed, ensuring rapid establishment of new patches of this excellent ground cover.
