I know that the other day, I questioned whether someone meant
'difficult to kill' by 'hardy', but the common usage would just be
one of cold-resistance. Probably people won't agree on a definite
dividing line, but for the most part 'hardy' means 'tolerates
freezing', while 'tender' means that temperatures must remain above
freezing (sometimes quite a lot above!).
Concerning the Pings that I grow, grandiflora, vulgaris and
lusitanica are hardy.
