Rozanne - no doubt. Because of her huge flowers and white centre of the flower. And it blooms until October-November.

Second vote..absolutely no doubt !!! Rozanne forever ! ;o)
BUT...Marlene (hello, dear !)..what about hardiness??? Deanna is in zone 5...You know better than I do...are you sure Rozanne will accept it? Would not Brookside be a more reasonable choice in this climate?

You are absolutely right, Zephirine (my dear!); I hadn't noticed that Deanna lives in Zone 5. So yes, 'Brookside' would be a better choice. It is quite hardy.

I live in an iffy zone 6 area. (Some charts still say we are zone 5) Rozanne does great for me. Blooms June through Septmember. Brookside only blooms about a month.

Rozeanne is fully hardy for me in zone 5b. But I prefer Nimbus over Brookside, though both have a shorter bloom period than Rozeanne.

I just bought Rozanne from Wayside gardens for my zone 5 Wisconsin garden. No one mention that the hardiness was iffy for this area. Should I mulch heavily or what?

Love my Rozanne. Planted it May 15th and it's been blooming non-stop. And tomorrow will be August 1st.
