Jerry: I'm in Northern New Jersey and I've had a Eucomis bicolor in the ground for 6 years. It originated at Ellen's nursery in Seneca NY. I comes up each year a bit late, but never has failed to make an appearance. This winter was not a Zone 5 by any means but it is survived last year which was a real Zone 5-6. Have a look. http://pacificbulbsociety.org/pbswiki/index.php/… Arnold
