We have a 2-acre property for a future house with a large flat area bordering on a neighbors lawn. It will be in full sun, pretty good soil, at the base of a steep slope, and I don't want to mow there. I need a ground cover that will spread pretty quickly but not encroach on his lawn. We have lots of vinca elsewhere on the property that I am transplanting onto the hill above this flat area to control erosion, and for the looks. We also have ivy at our current house that I could take and use on that area.
Any opinions would be welcome - more vinca, ivy, something better? Also, I have available lots of rocks I could use on the border to keep the cover from spreading onto his lawn.
