The trouble with the Crinum suggestion IMO is that Crinums are stay at homes, do not disturb, and the Irises multiply enough to need thinning (in some places, though not all).

I'm wondering if Iris xiphium (Spanish iris) might do better in your version of z7. The Dutch and English ones tend to need a temperate climate otherwise they fade away after a year or so. Continantal extremes are generally just too much.

As for the bulbs in the fridge, go on. Plant them. They'll probably be fine. And try the Crinum experiment. Perhaps the extra water will turn the trick.

An old friend of mine(95) told me to plant them at least 8" deep, and they are more likely to return. Also, don't forget to fertilize. That is the only way I can get most bulbs to return. Do it when they break ground and again when they are through.

I like that idea! It might be a way to stop them multiplying like rabbits - and being more faithful in flowering (thought they're pretty consistent).

Thanks flowergirl!
