zuzu, thanks for your comments. Yes, one needs lot of water for roses and this is one flip side of growing roses in hot areas. But then, we have the advantage of 10 growing months also.
Neal: Some of my DA roses have performed well in heat, just give them slight shade and they are good to go. Others include The Prince, Glamis Castle, St Swithun, The Dark Lady and L.D.Braithwaite.
Small size blooms with low petal count and no fragrance. Bush is growing vigorously .
Lot of blooms on Ebb Tide. Size is small and fragrance is less as compared to cooler months but the bush is blooming non-stop even in this heat. Very impressive.
Evelyn May hasn't been blooming very often after main flush in spring. Just a few odd blooms. Bush however is quite large and is 7 ft high at the moment. Short bloom life
Fragrant Charm has been unimpressive on multiflora root stock. Just a few bloom this year. Size and fragrance was very good in summers but just a mediocre now. Short bloom life
One of the better performers in high heat. In 14" pot. Bloom size is relatively small (3 to 3.5") and fragrance is less too but is quite noticeable, specially in the morning. Bloom life is very good and blooms last for 2 days or more. Very majestic....
