wow, that's uncomfy as far as hot & humid. Mid summer, we're talking mid nineties in the day, dropping usually in the 60s at night, humidity on a HUMID day around 60%, but usually between 10-20%. Gets dark around 9ish & full sun again around 6am. Kinda miss NNY.. in the summer it didn't get full dark until literally like 1030pm and was full sun at 5am! I could FISH!! But the tradeoff was in the winter.. didn't get full light until about 9am and got full dark by 4. :(
Mardi Gras is a rose that has been most forgiving for me. She just plugs along blooming all season for me. She's also the first to wake up in the spring & one of the last to go to bed for the winter. Not as strong a scent as some others, but definitely worth a gander at. You might want to check Intrigue. I don't know how he'll handle the humidity (as you can see, I don't have any), but extremely strong smelling and very generous with blooms once it gets going. Same with Heirloom.
