I will add it the list appears to have ended in Feb., 2018. Wonderworld is listed as a zone 5a in the database, but that is just the "evergreen" default. Very pretty. It is interesting that it is a more recent Stamile, I have read that they aren't as hardy as the older ones. The only EV's I have are Joan Senior and Entwined in the Vine...which have made it thru 3 winters here. The only Stamile I have is Night Embers and it is doing well, so far 3 winters, but it is an older one and it is SE. If anyone wants to add ANY zone 4 daylilies I will add them to a list (oh no another database!) and try to figure someplace to post it. I may have to join Facebook yet.
