    Fountain grasses are warm season grasses and will not green up at the same time your lawn does. Cut your grass down if you haven't already done so. It will be coming up when weather warms.

    Yes, this is how they are meant to propagate. By any means necessary. They will start up anywhere that they can as long as the environment allows for it.

    If they area is mowed frequently, or managed by hand, then you can control most instances before they are old enough to reproduce.

    There are several species that are called fountain grass. The African grass, Pennisetum setaceum in considered invasive, particularly in the western US. Pennisetum alopecuroides or Chinese fountain grass is listed as invasive in some mid Atlantic areas. In total, there are 6 Pennisetums listed as invasive. However, I'm not convinced we are talking about the same plant genus. Pennisetums produces a huge number of seeds that spread via wind. They do not have burs or awns for hitch hiking. A number of other plants do , however. Some are native plants, some invasive. Perhaps you can start a new post with a photo of the plant in question. A web search for plants invasive in Ohio may turn up the information you are seeking.

    I would give it a deep watering every week or so. Since it's in a pot with full sun, check the soil every few days to be sure it is getting enough water, though it is somewhat drought tolerant.

    Here are a couple of articles with ideas about how to give your potted fountain grass the best care.

    I think you would have seen foliage by now. Are you sure it isn't purple fountain grass which is also called red fountain grass? This one is not hardy in your area and is grown as an annual. Fireworks is a red variegated grass but it's not hardy in your zone either.
    I suggest replacing it with a hardier plant. Here are some ideas:

    This looks like Cenchrus setaceus, which is a Fountain Grass.
