Joe Shaw asked about Crinum along the Hudson River. I have no experience gardening there, but the old New Illustrated Encyclopedia of Gardening (c. 1960) edited by T.H. Everett illustrates its article on Crinum with a caption which states that Crinum x powellii is hardy as far north as New York City. It was this statement which prompted me to plant my first Crinum about forty years ago. BTW, when I first read Joe's post, I thought it said Hudson Bay! I think even Crinum x powellii might have trouble there.
