	I don't think this would ever come to my mind that northern/ 
hardier species are triploid or tetraploid.

	In Lycoris, L. chinensis is much hardier than L aurea and 
both have 2n=16. L. squamigera, one of the hardiest with 3n=27 is a 
lot hardier than L. radiata radiata (3n = 33) and both are triploids.

	There are a few peony pairs such as P. obovata and P. 
japonica; and P. wittmanniana and P. mlokosewitschii. In both pairs 
the first is diploid (2n=10) and second tetraploid (2n = 20), but 
their distributions essentially overlap.

	Further there are both 2n=10 and 2n=20 wild collected Paeonia obovata.

	Paeonia anomala, the very hardiest of all peonies is a 
diploid, too (2n=10)

	Hardiness doesn't seem obvious as an attribute related to 
ploidy? Any other examples?
