Neutral coriaceous On Jan 28, 2014, coriaceous from ROSLINDALE, MA wrote:

This is one of the hardiest crinums. I've read several believable reports of this being reliably hardy in the ground to Zone 5b in Westfield, IN and Platte Co, MO.

I've also read that hardy crinum bulbs need to be at least two inches in diameter before planting if they're to make it through the winter in the ground near the northern limit of their hardiness, in this case Z5-6.
