Pacific Northwest Gardening: Variegated Vinca advice, 1 by anastatia

Attached 2 photo's of variegated vinca I have on west side of my back yard.10 ft x 10 ft right now. I have an evergreen mock orange (to grow 8 ft tall x 8 ft wide) and a Peegee hydrangea along the cyclone fence where this vinca is spreading. I plan to plant a flowering quince & something else. Trying to create some natural privacy after pulling out old arborvitae a few yrs ago.
My question: Have I created an invasive monster by planting this vinca? I need to pull out the delicate Iris and lilies I have planted in this area as they are lost in this jungle. I thought I was creating a low maintenance
area. My dear neighbor on the other side of cyclone fence has a yard crew that must spray that area to keep it out of her yard, I am assuming.

What was I thinking?

I have same vinca on shady east side and grows very slowly.
