Q.I see different ideas on what kind of light periwinkle ground cover needs. Can you provide definitive answer?
I like to grow periwinkle as a ground cover in a pebble bed about 2 ft wide with a 2 ft retaining wall running about 80 ft long. I like to train the plant to grow up along the wall. I want to use the plant for erosion control.
I get full sun in the area, 8 plus hours.
I like to grow the plant with a large shrub (6 ft plus tall) for privacy if possible. I know periwinkle can probably overrun other plants, so I guess it is a matter of keeping on top of its growth?

They can take full sun or part shade. Here's an article from the Missouri Botanical Garden all about Vinca major, which grows well in your zone and would suit your purpose: http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=e212
