I just lost my reply to Judy because my iPad reloaded the page while I checked something on another tab
Tryng again...
On the north versus south thing, it's interesting to note that Stout, when he first described semi-evergreens, referred to the cultivar 'Chengtu' being deciduous/dormant in Florida but evergreen/semi-evergreen in New York. So it isn't just a north=dormant and south=evergreen thing because the reverse can occur. Daylily dormancy is not well understood.
The thing is that evergreen is a foliage term, semi-evergreen is a foliage term, deciduous is a foliage term, dormant is a bud/meristem behaviour term, so when the AHS switched years ago from calling them deciduous to calling them dormant it mixed up terminology for what is supposed to be foliage habit by making one a growth term. The current change brings the AHS back into line with normal horticultural/botanical language use for registration purposes.
