Heirloom Roses in Oregon is a good source for disease resistant varieties and they will help you decide which will be best for your area. They're not grafted roses and they are small plants, but they take off well. They have a sale in August with some good prices, but it may just be at the nursery. I don't remember since it has been a long time since I was there.

anuparaj,

Are you considering once-blooming roses (that bloom for a period of several weeks at the beginning of the summer) or only those that bloom all season long?

Several of the old garden roses do really well here. One of my favorites is "Rose de Rescht"--it repeat blooms, is fragrant, and is a great looking shrub with dark blue-green foliage. For once-bloomers, good ones include "Duchesse de Montebello", "Belle de Crecy", "Felicite Parmentier", "Charles De Mills", "James Mason", and a bunch more. If you like "Sally Holmes", you also might like "Lyda Rose"--and it will bloom its darn head off. Another place you can order the roses besides Heirloom is Rogue Valley Roses in Oregon. Bigger plants are available at the Antique Rose Farm in Snohomish, and they should be able to answer a bunch of questions, too.

A good place to check out roses is HelpMeFind.com. You can go to the roses section, search on a plant name, and see photos and all sorts of comments by members. Plus you can find out places to buy a rose--there's a "Buy From" tab.

I prefer repeat bloomers. :)

Rose de Rust is more like it. Nice fragrance, but...

Fourth of July- not very tall but nice flowers

OGR- Marie Pavie, Hyb Musk Cornelia, Penelope

Floribunda- Apricot Nectar, fantastic peach; Betty Boop, wonderful fades to different colors, always blooming
Buck- Distant Drums- wonderful display, myrrh fragrance
Ground cover- The Faun, Seafoam, Baby Blanket

Chortle, snerk, Plantknitter. I seem to have the same specialty!

The OP inquired about disease resistant variety. The Seattle Rose Society's recommended list contains only three that need "little or no spraying" -- and one of those is the extremely boring and competely non-fragrant, Knock-out. I find that list extremely unhelpful.

Grumpily,

I'm with Plantknitter and Blameitontherain with the specialty on spotted roses. Since I'm not trying to win a rose competition, I don't do anything about it.

My roses are on the side of the driveway thanks to the previous owners. They look great and bloom plenty but I do nothing but trim them down. I figure a little stress means less pruning and makes it easier to get out of the car.
