Re: Roses

Well, I have been growing Rosa rugosa 'Belle Poitevine' (pink flowers) and
Rosa rugosa 'Blanc Double de Coubert' (white flowers) as well as Rosa
damascena bifera (light pink flowers) for probably nearly 15 years and
never have any of them shown any blackspot or other problems bar the few
aphids in spring.  All are highly fragrant; bloom once (I know R. d. bifera
is *supposed* to rebloom in fall, but hasn't) and are not good for cutting,
but decorative in the garden.  I don't get the decorative hips on the
rugosas, either....but I'm not complaining.

They put up with partial shade, sporadic feeding and my hot, muggy summers
which are probably a lot like yours, if not worse.  They have been bone
hardy for me...I'm quite fond of these guys.  The two rugosas want to be
pretty tall plants.  My only complaint with the damascena is that I need to
stake it - but this could be due to its being grown in partial shade at the
foot of a greedy yew hedge.

I also grow R. glauca, primarily for the foliage, although the single dark
rose flowers are attractive in a quiet way.  Never any blackspot, but the
few Japanese Beetles I do get seem to hone in on her.  She does produce
hips and seeds around pretty freely.
