Vinca major is listed as a highly invasive plant in California. The University of California Statewide Integrated Pest Management Site defines Invasive plants in the following way. “The important biological difference between invasive plants and garden or agricultural weeds is the ability of invasive plants to disperse, establish, and spread without human assistance or disturbance. My way of keeping the vinca in check it to cut it back to the ground with a string trimmer a couple of times per year and to pull any of the plants that start to move out of the area where it is ground cover. Herbicides will kill it but you may need several applications, spread out over a few weeks, to completely eradicate it. Because the source of the vinca is not coming from your yard you will have to stay vigilant and remove or spray any new plants that emerge on your side of the fence. It comes up through thick mulch and if left unchecked, it can completely smother small shrubs and any annual or perennial plantings. It propagates itself from rhizomes (underground stem runners) and by rooting the stems above ground at each node. It was the main ground cover around the house when we moved in, and I have not been successful in completely removing it as it grows under shrubs and trees I want to keep.
