8. Panicum virgatum L. (N-Am.) – Increasingly planted for ornament (in private gardens as well as in public places) and sometimes escaping or found as a garden throw-out in road verges or on dumps. Recently seen, for instance, in Mol (see also http://waarnemingen.be/waarneming/view/49846843). In 1948 also recorded as an ephemeral wool alien in the Vesdre valley.
Perhaps often persisting for some time (dense perennial clumps) but probably not really becoming naturalised so far.
