I found an interesting e-page. See below.

Here is a link that might be useful: Saffron

Terry: That e-page is interesting, but did you notice that it says repeatedly "crom" instead of "corm"? I googled it just to be sure there is no such word, but Mr. Google never heard of it either. I would have thought it was a typo if it hadn't been in there so many times. Wonder how that happened.

Yeppers, I did notice the crom vs. corm. I used to co-edit a quarterly horticultural magazine and my proofreading skills are pretty good. My typing skills are lousy, though.

Check the link. Someone on Gardeweb has saffron.

Rayama,

I have tried several times to grow saffron in different soils to no avail. A dozen bulbs will flower well that first October. The following year there will be 4 or 5 and one the 3rd year. A few leaves the following year then nothing.
It could be rodents eating the foliage but I've not seen any evidence of that.

I did have good luck with the cartwright Crocus. It is the ancestral saffron. I thought it too had perished, then several years after planting, it began to reflower. This is in heavy clay soil in a cedar glade. The flowers look like saffron to me.
