Vinca minor
Common Periwinkle
"
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.
