Vinca Major, commonly known as large periwinkle, is a hardy evergreen groundcover plant with glossy dark green leaves and violet-blue flowers. It is native to Europe and northwest Africa, but can now be found all over the world. Other synonyms for Vinca Major include bigleaf periwinkle, greater periwinkle, blue buttons, and myrtleleaf. Despite its beautiful appearance, Vinca Major is considered an invasive species in some parts of the world, as it spreads rapidly and can choke out other plants. However, when properly maintained, it can be a stunning addition to any garden or landscape.
