Found I believe a future new release in the Canadian artist series on this hunt into Canada zone 10. Named after the famous Canadian Jazz artist, Osacr Peterson. Row upon row very very young roses not yet ready for sale or wholesale probably next year. White semi double as an immature rose. Canadian landscaper association etc effort I believe. Can not find in helpmefind or web, if anybody knows more please share. Photos when I return for those interested.
Yes, please do post pictures when you return.
I wrote a very brief history of the Canadian Artist Series which can be read at
or the file is available to all RHA members through their membership pages.
Field of dreams, but not for sale so I did not acquire an example, but did acquire AC28 which is very fragrant therefore important for the future.
I hope there are fields full of them destined for bare root sales, as well.
I don’t know this rose looks like thousands I’ve rejected. It surely don’t have the" WOW!" factor to me.
Or maybe I’m just green with envy.
The individual flowers aren’t glorious, but large, and the plant architecture looks good for a shrub. With disease resistance and hardiness, this rose could make very showy mass plantings. Hardy repeat-bloomers in white are pretty rare.
Peter says: “Hardy repeat-bloomers in white are pretty rare.”
It will be tough to beat White Out for a combination of health, hardiness, shrub form and bloom power. Although Oscar appears to have shiny foliage.
I see another potential plus for Oscar, albeit it is young, but like Golden Wings the pistil stamen anther etc. is going to add to it’s interest, unless they stay “small” and age in a day.
I agree with Charles. It’s not a rose that appeals to me and I wouldn’t be interested in growing it. White roses aren’t as popular as other colours. Therefore, they have got to have something exceptional about them to make them attractive to purchase, and this cultivar doesn’t appear to have it.
I think Peter is right that this cultivar might be useful for mass plantings (in parks and green spaces). A contrast of it and, for example, the red ‘Champlain’ would likely be a magnificent sight to see. But since it likely is only crown hardy for Zone 3, this wouldn’t apply for such a cold climate because the maintenance costs would be too high.
Sales of roses in Canada are way down. The market just isn’t there for conventional looking shrubs anymore. Roses need to be developed for growing in small landscapes and containers. I trust the Vineland rose breeding program is heading that way.
I would of bought it in a heart beat but no amount of bartering with unter gruppenleiter would prevent das order from Uberleiter that retail will not transgress into wholesale property and vise versa … for being probably for the same reason I bought MT another … pink rugosa from Robin … Oscar has merit and skill showing in the leaves and early form and I need a shorties up front like Robin’s Jamie an interesting mauve shorty … mind you my preference now a days is for rose that makes a tall grand broad sweeping statement and chokes me with the fragrance of the gods, not one I have to crouch down on arthritic knees … small may go against Oscar in the long run … but I have a use for him.
Yeah that whole bending over thing may lead to selection for taller roses despite our proclaimed intentions of breeding for low growing roses.
I can’t count how many first blossoms I’ve plucked off because I want to smell them but don’t want to bend over that far.
“…chokes me with the fragrance of the gods.” Love it! Definitely a worthwhile breeding goal!
I noticed today Cornhill has it in its spring lineup with following notes - “complex parentage” “perhaps best non suckering hardy white” … likely to be debated by some
It’s likely ‘Oscar Peterson’ has equal if not more value of a landscape rose, when used in a breeding program to produce roses having yellow flowers. It has a yellow parent (‘Yellow Submarine’) and if combined with another yellow, there is more chance of producing yellow progeny, of course. It’s reported the shrub is upright in its growth habit. If so, perhaps this is because of Rosa carolina and R. virginiana in its pedigree. I like the idea of transferring this trait to yellows, since, for example, new cold hardy ones like ‘Bill Reid’ are a typical looking yellow Floribunda. I’m tired of them. I want to see a more interesting and aesthetically appealing yellow shrub rose in the landscape. Of course there are other avenues to pursue this goal, but I think it’s possible this could be one of them.
Jeffries Nurseries description - “Upright, pillar-type rose of 3’ height and 3’ width; highly disease resistant foliage.”
That’s not my idea of a “pillar-type” rose, but judging by the photos on the website it is upright. Add a Rosa laxa hybrid to it, say Rosa laxa x ‘Hazeldean’, for example, and then maybe a true Pillar rose can be developed. And a cold hardy (Zone 3) yellow one at that. I would also give J5 (‘Prairie Magic’) a shot at it.
Planted Oscar Peterson this spring, and it has been a vigorous grower, blooming well but at the moment is afflicted with powdery mildew. The Olds College Centennial Rose planted beside is not, time will tell.
" I’m tired of them. I want to see a more interesting and aesthetically appealing yellow shrub rose in the landscape"
Sure agree with that statement Paul…give me a healthy fragrant rose that I “look up” to…one that I can wander underneath…one that makes a statement that it has been part of the landscape for a long time…and has earned it’s rightful place physically and aesthetically. I see these traits more in OGRs.
Jim Coutts of Unity , Saskatchewan reports ‘Oscar Peterson’ is susceptible to powdery mildew and as a result the shrub is unattractive looking. so it seems nothing yet has beat my ‘Prairie Snowdrift’ (sport of ‘Morden BLush’) for a white rose growing in a Zone 2/3 climate. Unfortunately, it’s not widely available. However for Americans, High Country Roses in the States sells it. Ironically, ‘Morden Snowbeauty’ (derisively known as ‘Morden Nobeauty’), a less attractive white rose and more prone to disease is commonly available. All is fair with love but not roses.
