I just pulled out a ton of vinca vine from a large raised bed (and yes, I know...I'll still be pulling out the newcomers for years to come!). I plan to re-plant it around the side and back of my house where it slopes from the house down to a wooded area. I really need a ground cover in this area, because of erosion, and it's very shady. I figured the vinca (especially since I already have it) would be a good choice. However, I was just reading the thread about "plants you wish you'd never planted", and saw that a lot of people hate vinca. Would this sloped area adjacent to woods be a good idea? Does vinca have a negative impact on woodland area? This is not an area that I ever plan to clear.
