Each spring I get plant catalogues selling small plant material and seeds. Most of the plants are good and I definitely like some. One can get trees like Pawpaw or Persimmon that are not easy to find elsewhere. However, some plants are bad. This ia an add for Royal Paulownia, of the catalpa Family, that has escaped cultivation in se PA and is invasive, plus a fast growing, messy, brittle-wooded tree that is not worth growing.
