Vinca minor from stem cuttings?
I have a friend with a very large area at the base of a small hill, 1200 square feet, that he would like to cover with vinca minor. With the large number of plants that would require, purchasing them from a nursery would be $$$. A neighbour will allow him to take cuttings from his sizeable vinca patch, however.
Would it be workable to take cuttings and try to root them in water for planting?
Thanks for any advice you can offer.
