A great Fragrant beauty that I'm sorry I ever gave away

Zephirine Drouhin...very pretty, nice fragrance and no thorns!

New Dawn is very nice, but I've been warned the thorns can be a bit overwhelming, especially if you need to get past the rose. May be better for the back of the garden...although Florence has a lovely combination with Viking Queen :)

Goes without saying Zephirine Drouhin is my very favorite rose but in some areas it tends to get BS----what part of N.J. are you in?--I'm right across the river from Trenton in Yardley-----

It blooms early and the fragrance is divine----

njmomma, I was going to mention white "Maman Cochet" until I saw which zone you lived in.
If I understand you correctly, you can only buy one plant, which would mean it would need to grow to be c. 20 feet tall so it could grow up, over, and down the other side of the pergola.
I've never grown "Deuil de Dr. Reynaud" but its the type of Bourbon I love, rose-pink bordering on cerise, showing a luxerious plushness of bloom.
la brea: 3 questions about your rose
- how healthy is your "Deuil de Dr. Reynaud"?, must you spray it?
-how big does it get?
-what type of fragrance does it have?
It is said to be floriferous and fragrant, which would get my vote for a pergola.
njmomma, I've searched for D. de Dr. R" , it is presently available from roguevalleyroses.com, if you decide on buying one.
There is a modern climber that I love because it has a more natural bloom style than a typical modern H.T. and reminds me somewhat of the Old Garden Tea named "Anna Olivier" but it is more cold hardy, it's called "Autumn Sunset" and it re-blooms better than any other modern climber that I've ever seen, in shades of apricot, pink and yellow and buff-tan. Hortico often sells it. Like many climbers, it takes 3 years (sometimes 4) to reach its full size which in your climate zone could be c. 20 feet tall.

I'm a big fan of 'Compassion' too. This is a rather stiff and upright rose so you would definitely need two; one for either side of the arch. 'Compassion' takes a few years to get going in zone 6, in my experience. It was cut back quite a bit by winter cold the first year or two, but once it gets some size to the root and canes it is very winter reliable.

New Dawn has nasty thorns, is a fairly stiff rose, and gets enormous and heavy, none of which are good for sitting under situations. You want something more along the lines of Zephy: thornless, flexible canes, more "mannerly."

Zephy looks great, but I'd like something less vibrant colored - I prefer light pink or light apricot. I'm thinking maybe Eden or Nahema or Abraham Darby. I like the cabbage shape of those blooms too and the colors speak to me.
Thanks!

A polyantha rose would work very well for you, or even one of the smaller ramblers like Phyllis Bide or Ghislaine de Feligonde. Madeleine Selzer is a nearly thornless white rambler and also Paul's Perpetual White (related to a moschata) is also fragrant and more continously in bloom. Gardenia, flexible and well covered, also fragrant. Finally, a red rose I have always liked is Chevy Chase. A more modern rose, but with perfect nodding blossoms is Ena Harkness - all these should be hardy for you. Hmmmm, only one! not very helpful, all this waffling on....but hey, you could stretch to 2, one on each side.

'Ghislanine de Feligonde' is an upright pillar rose, although as it get older it can get longer more rambler type canes. It is reliable and hardy and an excellent all around performer; truly an outstanding rose.

njmomma,
Which rose did you choose for your pergola? How's it doing?
