Your plants would fall into the concept of pubescens, at least to my eyes. That said, the delineation of this species into the more or less accepted varieties, v. parviflorum, v. pubescens, and v. makasin, are based largely on plants from populations east of the Mississippi River. Plants in the western US and far north don't always fall into those categories easily, and indeed even many eastern plants seem to be intermediate forms.
If you want to see kentuckiense I'd contact someone who knows a population and is willing to take you to it. They are rare as hen's teeth, even in the heart of the species' distribution in and around the state of Arkansas. I've only seen cultivated plants, but they are something to see in person.
