The plants were planted in the late summer or early fall. Nothing was planted later than the first week of September if memory serves, I would have to double check to make sure.
Plants that lost fans were mature. Several of them ... have been in my garden for several years.
Being in Zone 4 my winters are quite long and severe - snow does not disappear until mid April and the last killing frost can be in early June. To be certain that my daylilies survive their first winter I plant new arrivals before the end of June.
Although a cultivar may be mature in that it has been in the garden for several years and has bloomed on multiple scapes, not all the fans in the clump are necessarily mature or the same size. I have a handful of cultivars that are not completely hardy in my conditions. They produce new fans but those fans do not usually grow large enough during their first growing season to successfully survive their first winters. It tends to be younger, smaller fans that do not make it through their first winter in those cases where hardiness is borderline. That is often the case for evergreens here. Nearly all evergreens will do fine as long as they are planted or divided in the spring. Some will be decimated if they are disturbed any later than June.
