Quietness is only very slightly fragrant to me and to most folks. It's a good one, though.

You should add your state or province to your header. Disease pressure in Montana is very different from disease pressure in New York state.

I don't know of any repeat blooming roses that are both very fragrant and very resistant to black spot. The once-blooming Gallicas and Albas are great choices for zone 4.

I have had Roberto Capucci for two seasons, and am very happy with it. It has large fragrant blooms that last a very long time, and mine shows less disease than most of my other roses, but I do spray.

Quietness has light to moderate fragrance to my nose. The bush has better than average disease resistance around here. Makes a good cutting rose and repeats well.

'Distant Thunder' has blossoms of pinkish/lavender tones that contrast beautifully with its burgundy-hued stems and foliage. It's been in my garden for 3 years and was very small when it was planted since it came as a tiny band from Heirloom. It's taken this long to become established and this past summer it finally started blooming well for me.

I can't comment on the BS resistance since I spray, but it is a very lovely and graceful bush.

I got Quietness in 2005 from Chamblees. The plant arrived in bloom, and imparted fragrance to the whole order of maybe half a dozen roses.

I had read that Quietness was only mildly fragrant, so I was quite surprised. In fact, I purchased another soon after.

However, I would say that Quietness' fragrance definitely comes and goes. It seems that you have to catch it at the right time. It is a beautiful rose, though.

I've attempted 'Roberto Capucci' only once, so perhaps my experience is atypical. It's a lovely rose with imressively large blooms, but I found that it was NOT hardy even in my relatively warm zone. If you attempt it in your zone 4 garden, I suggest that you plant it as early in the spring as possible, and then take extra precautions next fall to give it protection from your winter conditions.

I too was surprised by Quietness' fragrance. I thought it would lack fragrance, but I'd say it's moderately fragrant. I don't get any disease on mine.

Hi! I love Quietness ~ You can read my posting about my experience with this favorite rose.
I agree with aegis500 - the fragrance comes and goes.
