After hearing hearing all the stories about hot gardens i feel pretty lucky growing daylilys here in the midwest where cold winters kill rust spores and 100 degree days are very few. In fact we have yet to have one this year. A few weeks ago we were under average temps at low 70's for daytime high and now we are above the average for this time of year at at high 80's so we never know what to expect as one year is never quite like the next and sting can be a crap shoot also.
Have some plants at back of house morning sun only and doing very well. Chicago Apache was stunning in part shade getting bigger and blooming more than i ever seen it do. Have some under a pear tree for dappled afternoon sun and they are not doing well at all. Vast majority in full sun most of the day but with worst summer being drought and mid 90's we are better off than the deep south or southwest would be at any given year.
Was always a bit jealous of southern growers with all the mild weather during winter but now i have come to realize that we up north can always start anew with reinvigorated plants, chilly and rainy spring time and most summers that do not try to kill off everything green.
I think part shade can be a good thing even up here as long as its not too far under a tree where the poor plant is forever trying to reach for the sun.
