Commonly known as blue periwinkle, greater periwinkle, or bigleaf periwinkle, is an evergreen perennial creeper distinguished by its vigorous, mat-forming growth and attractive violet-blue flowers. Native to the western Mediterranean, it is now widely distributed in temperate regions around the world.
Invasiveness
Vinca major is considered invasive in many parts of the world, including North America, South Africa, Australia, and New Zealand. It spreads rapidly by rooting at stem nodes, forming thick mats that crowd out native plants and alter habitats.
Environmental Impact: Dense growth suppresses biodiversity by excluding native flora and degrading animal habitats, especially in woodlands and riparian zones.
Propagates vegetatively—fragmented stems root readily, and water or garden waste can transport viable pieces to new locations.
It is relatively easy to eradicate by simply pulling out all growth when seen. It grows back quickly, so growth needs to be removed monthly until eradicated.
