>> we can and should look seriously as those "interesting, but NON-marginal" plants to be an important part of our landscape <<
Where I live, Zone 7a, is basically the "balmy" part of Humid Continental Climate. Zone 8a (200 miles south of here) is definitely Humid Subtropical. 8a is where you first see palms growing unprotected, out in the open, not hugging buildings for additional warmth.
In 7a, even Needles & Minors will suffer greatly in the worst quarter of our winters.
However, there are plants that are rock solid hardy here that are interesting. A partial list would include: Japanese Umbrella Pine, Daphniphyllum Macropodum, many species of Yucca, Opuntia, Aucuba, various Bamboos, Photinia, and Ponciris.
A 7a gardener can conjure up a very "palmy" looking landscape through the use of leafy Yuccas and bamboos, never having to utilize a single true palm.
