I'm looking for a fast growing non invasive ground cover that won't take over my whole garden ... partial sun and no more than 6" tall. Do any of these qualify, or is there something better? Aubrieta Blue Star Creeper Creeping Mazus Periwinkle
Fast growing very often equals invasive. I don't know about all the plants you mention, but Perywinkle is considered very invasive. From my experience, I would recommend: Barren strawberry Waldsteinia fragarioides Whitley's Speedwell Veronica whitleyi all kinds of low growing Sedums and Thymes Creeping Phlox Phlox subulata Moneywort Lysimachia nummularia
