Some background: Richmond VA. Black spot dominant
I have read so many mixed reviews on this roses that now I am confused.
Is anyone growing DA Fair Bianca in south or humid area? Is she a prolific bloomer- frequent repeats? Is there good vigor?
It's hard to find FB on sale and I found a source who has her, but is she is
I don't spray for BS.
Thank you all

I have 2 in my garden, she's a prolific bloomer, no problem so far. But I'm in SoCal, mostly dry and not humid.

Thank you, SoCal!

You need to seek advice from your local rose society. Black spot strains vary from place to place. So a rose may do well against the strain I have here in Michigan but may be a disaster in your area. Only local experience will let you know that.
