Is vinca invasive?
Vinca is not native, but is an excellent ground cover recommended by many landscapers. However, vinca is very invasive. In cottage country, I’ve noticed that it has overtaken entire fields, eradicating native plants. Once established, it is very difficult to remove.
It is very tolerant of sun and drought, so can be a great ground cover, if you like it and can control/contain it. It does not use more water and nutrients than similar ground covers. It can, however, encroach other plants if not vigorously controlled. If you wish, manually remove it; I’d suggest planting native mosses as an alternative.
