mouldy Iris winogradowii

Iris winogradowii is a royal pain to grow! It is an
alpine bulb and needs as cool as summer as possible
without drying out much. Those sorts of bulbs don't like
our eastern US summers, with attendant heat and humidity.
I have it in a couple of spots and two of the bulbs
flowered again this spring, to my surprise. They are in a
bed with Trillium, Sanguinaria, Corydalis of the solida
section, Frit. camschatcensis - things that want a cooler,
dryer summer but not drought. The bed is in reasonable
shade and in winter freezes solid - cold and ice is no
problem!

I hate to be the merchant of doom but I doubt you'll ever
see this one above (or below) ground again.

Good luck.
