Floribundas are fine. Some are more disease-susceptible than others, but they should all grow and flower well.

Hybrid Perpetuals -- another matter altogether. They'll all require regular spraying for blackspot. I've never found a resistant one. And some of them will be only once-blooming, even though they repeat elsewhere. For good repeaters in Florida summer heat, I'd recommend 'Paul Neyron', 'Baronne Prevost' 'Frau Karl Druschki' (give her space -- she's huge) and 'Reine des Violettes', which may not repeat the first year, but with maturity, should repeat. We had a handful of flowers on ours today, I noticed. Oh, 'Marchesa Boccella', a.k.a. 'Jacques Cartier', and variously classified as a HP or a Portland, is a good repeater in the heat as well. Again, he'll need spraying for blackspot.

Thanks for your suggestions, Dr. Manners. Your reply has been "clipped"!
