Hardy Nerine bowdenii

But, Jim, losses were caused by water during their winter dormancy and not by lack of hardiness.

In the spring I found only a half-dozen bulbs still alive. I put those
into pots and have kept them in a greenhouse over winter since then. These
are the ones I call "Koen's Hardy" and they are much more reliable bloomers
than most other strains of bowdenii I have tried. They are just not
reliably hardy here, unfortunately -- 15% survival is not very good.
