I don't grow a whole lot, but Intrigue is pretty fragrant, and Sheila's perfume, although Sheila's is not particularly disease resistant for me. The one floribunda I am really really impressed with is Regensberg - not terribly fragrant but it is such a blooming machine - it gives me two more flushes than any of my other roses. The new buds appear while the old ones are still on the bush. Amazing. I bought three of them at Home Depot at $6.47 a plant and still can't believe my luck.

Floribundas overall aren't known for being particularly fragrant but here are some that are definitely worth a sniff: Our Lady of Guadalupe, Angel Face, Day Breaker. I'm not in your zone so can't advise you on regional hardiness or disease resistance, but of the 3 Our Lady would be the most disease resistant but perhaps not winter hardy. Btw, there has been much speculation regarding the connection between disease resistance and fragrance. The talk being that the more fragrant a rose the more disease. Of course I've grown some not so fragrant roses and they certainly weren't disease free, but it's something to think about.

Cherry Parfait is a Grandiflora. I planted mine bareroot from S&W years ago and I love it. I detect no fragrance though.

One of the best sources for quickly finding fragrance listings is to go to vintagegardens.com and check under
Florabunda
They list each Florabunda, with its' intensity of scent and carry many varieties that arn't sold elsewhere.
I like the photos' I've seen of the Florabunda 'Centenaire de Lourdes' and it is of interest to me because it is closely related to an Old Garden Tea rose, Mme. de Tartas. If I lived in a colder region and couldn't grow Old Garden Teas, I'd grow that rose.
Of Florabunda roses I've known and grown the most fragrant are
'Margaret Merril' a beautiful pure white rose, 'Ebb Tide' which is purple, and deeply fragrant, but didn't rebloom much, and 'Orange Sensation', which is one of the most floriferous roses I've ever seen, here it grows to be a wide bush of 4' by 5' wide and it's very healthy, here.

Best wishes, for fragrant florries,
Luxrosa

Seems like Carla is right. Cherry Parfait is considered a grandiflora in the U.S. and a floribunda in Europe. Mine, in its first year, looks more like a floribunda, but who knows what it will look like in a couple more years.

At any rate, a good rose for you to consider, regardless of its classification.

I love Dusky Maiden, a dark red single that smells great and blooms like mad in my no-spray garden.

Colleen

Since no one has mentioned it, Apricot Nectar is very fragrant, as are Ivory Fashion and Pink Chiffon. Perhaps these have been superseded by the Austin roses, but not in the fragrance dept -- and they are good for cutting and very lasting in a vase.

Maybe they wouldn't be hardy in zone five though, unless well protected.

Perrenialfan, Luxorosa is right about Centennaire de Lourdes. It's a great rose with no problems, likes to be pruned and blooms alot. I detect no fragrance. It came from Ashdown. Here is a pic before it's pruning.

I just love Honey Bouquet, which tolerates our humid heat well. Beautiful color, very fragrant and repeats well. It is not, however, disease resistant. I grow it anyway!

Julia Child is a yellow floribunda with a strong licorice fragrance and it's a very good bloomer in our area.

Colleen:

May I ask how big Dusky Maiden gets? Wider than it does tall? If you have a picture I'd love to see it.

Thanks.

Kate

Kate,

Mine is a three year old own root, currently a little over three feet. The bush shape is gently rounded.

Don't have a picture but HelpMeFind has some.

-Our Lady of Guadalupe
-Scentimental

Those are the most fragarent floribundas I have. I really like floribundas too. In my Florida garden they seem to do the best. Better than the hybrid teas, grandifloras, and even Old Garden roses I have. I do love all types of roses though and try to grow them as best I can.

Day Breaker
Our Lady of Guadalupe
Sheila's Perfume
Outrageous-Great fragrance, kind of wimpy grower for me...
Honey Perfume

For the life of me, I don't get much fragrance from OLoG. Great bloomer, though.

My most fragrant flori is Soft Morning, but it isn't disease resistant and I don't know how hardy it is in colder zones than mine.
{{gwi:323801}}

An arboretum visitor brought a spray from grandiflora "Kiss Me"-- wonderful fragrance and a very pretty informal bloom. HMF says it was bred from Westerland-- so you could probably expect it to be cold-hardy.

I don't know how disease resistent Scentimental would be for you, but it's tough to beat this one for scent. Angel Face and Love Potion, though, are at it's heels. Also, Judy Garland, a great older red/yellow blend Gruss an Auchen, which might be the oldest floribunda (1909).

Sheila's Perfume is pretty fragrant, but it mildews here.

Outrageous
Irish Hope

Both have nice fragrance and are disease resistant here. I think that your challenge will be finding the floribundas that will work in your zone.
Diana

Colleen thank you for the information on Dusky Maiden. I'll check that out a bit more.

Kate

You know, I just did some research on these and I'm amazed that nobody has mentioned Ebb Tide or Julia Child. Those were the two that were recommended to me, and the people I talked to had nothing but good things to say about Julia Child. I don't know what types of floribundas everyone else grows, but I think we have a winner with Julia Child.

Looks like you have a lot of floribundas to choose from. Pick your colors and go for it. There are several listed already from folks who live in your cold zone.

Only really fragrant floribundas in my garden, Intrigue (mauve) and Sunsprite (yellow), but alas, the bloom life too short. Floribundas fare well very in my climate, almost as cold as yours, but winters not as long, not as humid. I couldn't say how these would do for you. Julia Child is on my wish list, I chose Brass Band this year instead. Happy with my decision. I think maybe BB will have way more blooms and JC would have had more fragrance. Gotta find another place for her. Tried to talk DW into Julia Child for Mother's Day, but she wanted Tuscan Sun.

Best wishes,
Gary

I have had good luck with these smelly floribundas:

Honey Perfume: one of my favorites, lots of blooms, smells great. Honey/gold/yellow

Enchanted Evening: this is my first year and I am in love with this rose. Beautiful lavender, large blooms, and smells fabulous. Very clean, upright growth. I will order another one...a healthy, sweet scented, large bloomed lavender rose: winner!!!

Flirtatious: I've had this one for 5 years and it's one of my all time favorites. ALWAYS blooming. Nice, sweet scent.

Julia Child: a happy, well behaved, clean, rich yellow rose with a sweet scent.

Moondance: This is a beautiful, sweetly scented white rose that I've been very happy with. I love the scent.

Queen Elizabeth is ridiculously healthy and vigorous. Absolutely problem free, healthy, upright growth, always blooming. Sometimes it has a light, sweet scent.

Another recommendation for Julia Child. A licorice-y smell to me. I also have Heaven on Earth (bought it from JP) -- a very English looking rose, apricot, and a wonderful fragrance. Love it. Our Lady of Guadalupe is not very fragrant to my nose, but lots of blooms.

I sp-ed Sheila's Perfume. The blooms get old and nasty looking after they bloom out. Ugly. Scentimental does have disease issues for me. Dropped all of its leaves this past season. The fragrance was also inconsistent.

Sunsprite's blooms melt in one day. Not worth it. Shovel pruned. Two years ago, I decided to try a couple of Austins and have been hooked ever since. Nothing beats their fragrance. CJ

Simply Marvelous is my most fragrant floribunda. It's purple, with nicely formed flowers. Mine is on Fort. rootstock so is very vigorous. I have three, which should tell you how much I love them!

I'd like to chime in with Honey Perfume and Apricot Nectar too. They are disease-free for me.

I love the colour of HP, rich golden yellow when new, frothy creamy yellow as it ages. Never goes ugly. Loads of bloom. Do NOT deadhead other than the spent bloom, as scores of buds come up from immediately under the old bloom.

AN also blooms prolifically with large flowers spread all over the plant. My only criticism is that it doesn't seem to have a lot of leaves.

I forgot to mention Scentimental. It is hard to beat when judging a rose for fragrance. Also, my bush is very generous blooming and the flowers are large and last a long time. It is a very good floribunda.
My Moondance bush doesn't have any real fragrance that I can detect, though many people say that their Moondance is quite fragrant.
