I wish I knew where you live and what type of vinca this is. If it is Madagascar periwinkle, Catharanthus roseus, then it may be shutting down for the winter. It is only hardy to zones 10-11. The Missouri Botanical Garden suggests taking cuttings and bringing them indoors for the winter. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=a569
