i wonder if this is temperture related--some of these transplanted ones will develop the little suckers (miniature plants) on that leafless stem, since in 30 years i have never seen one, in NY!

In china town grocery stores, you can buy a 1 lb. bag of dried daylily buds.. they sort of taste like green beans, but sweeter.. they are used in "hot and sour soup" and many mixed vegetable dishes.

common daylilies are common in NY too, and are hardy to the middle of Canada. some think they are originally from China, so they might be common in europe too.
