Vinca minor (Common Periwinkle)


Michael's Opinion

I once used this plant profusely and in fact visitors to the A.M. Cuddy Gardens in Strathroy may still see large planting beds of it under the famous Ulmus americana. It was used and still is by others today because it is a very effective groundcover, rapidly covering the area with an impenetrable mat. That said I have seen it spread into large woodland stands, suffocating the native flora. These escapees are often from gardens bordering on such natural areas or where people have dumped landscape debris and the clippings of Vinca have taken root. Some of the cultivars (often variegated forms) are less vigorous and may make ideal substitutes for the straight species. Use with caution, ideally in parking lot islands where escapees can be driven over.

Description and Growing Information

General DescriptionMat-forming creeper found in shady locations, often used as ground cover. Stays a evergreen under snow. Has a habit of growing further than its intended planting bed.
ID CharacteristicBlue/purple flowers in spring, shiny, elliptical evergreen leaves on trailing stems, rooting at the nodes. Often mistaken for Purple Wintercreeper which do not root nodally.
ShapeMat-forming groundcover.
LandscapeUsed for ground cover in moist, shady areas at foundations, planting beds, often seen under woody plants. Attractive spring blossoms.
PropagationPropagate by rooting semi-ripe stem cuttings in summer or crown division.
CultivationGrows best in partial sun to full shade in moist, well-drained soils, and is adaptable to pH and drought. The foliage will become chlorotic in full sun and the plant may fail.
Pests Phomopsis livella (dieback) can become a serious problem.
Notable SpecimensThe A.M. Cuddy Gardens, Strathroy, Ontario, Canada.
HabitatWide spreading, evergreen ground cover found in shady areas with moist, well-drained soils.
Bark/Stem DescriptionNon-woody stems which are slender (2 mm in diameter), light to dark green, smooth, and somewhat glabrous.
Flower/Leaf Bud DescriptionBuds appear in April after developing under the mat of foliage. Purplish, lanceolate buds, 1 cm long, on erect shoots.
Leaf DescriptionElliptical, small (1-5 cm long) light to dark green leaves, in both a spiral and opposite leaf arrangement.
Flower DescriptionSolitary, perfect, purple flowers originate vertically from leaf axis and bloom from early spring to mid summer. Pinwheel formation, 12 cm in diameter with a five-lobed corolla.
