I don't think the one laying on paper is switch but I think you likely have some there by your hand in the other photo. It'll come Foggy, you're a guy who researches things enough that you would have nailed the older style switchgrass plantings easily enough. The new, improved varieties can have great success without all the prep required from the older varieties. You did everything right, you'll have 4-5' switchgrass next year if you keep the broadleafs out of it.
