Five hundred plus blooms sounds like a great start. The vast majority of mine are in full sun most of the day but i have several at the back of my house that get only morning sun one of which did better then i could ever imagine when i moved it from full sun to only morning sun last year..
Sounds like no matter where you plant none will be starving for sunlight. I would only suggest that if you have some that tend to lose their color faster than others that morning sun only might be best for those.
As for the semi-evergreens we have only total die back each year with winter temps at -10 to -20 at times.
Now that you have caught the dayliliy fever there is no cure so might as well make room and plan for more.
