Don't divide bearded Iris when temperatures are likely to freeze. They
won't anchor themselves, (due to frost heave). In any case the roots don't
grow when the temperature is near to freezing. you can get round this with
a frost free greenhouse.  English Cottage is a very good garden plant which
flowers a lot, but the flowers have poor substance, (-they are  easily
damaged by wind and rain).
Nor do they root in very arid Summer conditions but you can get round this
by mulching with  gravel.
