I'm wondering if there is super hardy plant that I could grow on some of my roads that are used infrequently enough that gravel is not a smart option. Right now, these routes are muddy messes. We plant to put a proper crown on these roads a little later in the year when they aren't such a mess. There has been a lot of talk of gravel, but I would really like to plant some kind of durable plant instead. Any ideas?
