Jim, Crinum 'Mrs. James Hendry' has thrived in gardens in Greenport, New York (Zone 7a) and Bloomfield, Missouri (Zone 6b) for the last 5 years, including last January's deep freeze, so it has respectable cold hardiness. I'd think the new hybrid will do as well, maybe even better. Regards, Jay Jim Shields wrote: >Looks like a very nice crinum. How hardy to cold is the pollen parent?
