Re: 'Chinook Sunrise' met its sunset

I didn't think the quality of 'Chinook Demise' er 'Sunrise' could get worse but apparently it has. At least regarding shrubs of it growing in the St. Albert Botanic Park rose garden (located near Edmonton, Alberta) that were all chlorotic, and this is a rose garden where the shrubs grow the best in ...

Re: Jens Munk rose

"Why has such a hardy rose as the Jens Munk almost disappeared from production?

Re: 'Chinook Sunrise' met its sunset

It seems to me that 'Chinook Sunrise' is an example of the danger of focusing on flower colour (unique in this case, but very underwhelming in appearance) and not considering all aspects of the flower. It doesn't have good flower size (although there can be a place in the landscape for roses having ...

'Chinook Sunrise' met its sunset

I had to try out Vineland's 'Chinook Sunrise' introduced this year, of course. Major disappointment! Small, essentially single flowers of light orange/yellow with a pink tinge that fade to white within three days. A "riot of colours"? Maybe a riot at the garden centre with customers demanding their ...

Re: Kind of starting new

Comment in HMF Roses. "I don't grow this rose ('Schneezwerg') personally but it is commonly grown in the U.K. and always looks happy and healthy, sometimes used in landscaping planting." The addition of a species to Rugosas can make them healthier. The prime example, of course, is Rosa wichurana ('M...

Re: Kind of starting new

Joe, I'm surprised you have had difficulty getting 'Hansa' to set hips. I've never had a problem with this Rugosa cultivar in this respect, and I've used shrubs in different geographical locations ranging from Edmonton, Alberta to Northwestern Ontario. 'Hansa' has always been a favourite of mine to ...

Re: Canadian rose breeding news

If Vineland thinks Russia is going to be a big market for its roses, it might be in for a big disappointment. Countries like Canada and the U.S., which have sanctions against Russia, are not allowed to export products like meat, fish, fruit and vegetables to it. So Russia would allow roses to be imp...

Re: Canadian rose breeding news

Philip, There is quite a bit of variation of the cold hardiness of the Explorer Rosa kordesii rose cultivars. For example, 'John Cabot' is perhaps the least cold hardy. 'Frontenac' and 'William Booth' are probably the most cold hardy. So if the new rose cultivars in this breeding program are compara...

Re: Canadian rose breeding news

The author of this article, Steve Whyshall, wrote: "If all goes to plan by 2018 the first of the super-hardy Canadian roses will be introduced." In fact, these roses aren't "super-hardy." Super-hardy roses would be ones totally cane hardy to Zone 2. Since much of the germplasm used in the Vineland r...

Re: Fall Newsletter

Andre, I agree with you that 'Golden Arctic' appears to have superior cold hardiness for this type of rose. I saw it growing at the Ag Canada Morden Research Station a few years ago, which is Zone 3b, and I noted it was crown hardy. The shrub was flowering quite well. Regarding the "elusive hardy cl...

Re: Hardy ramblers from R. laxa

Charles, One problem 'Isabella Skinner' has is that it can be very susceptible to blackspot. I once attempted to propagate this rose cultivar by softwood cuttings under an intermittent mist system, but I had no success because the cuttings were immediately hit by blackspot. I don't recall encounteri...

Re: Hardy ramblers from R. laxa

Thanks Margit for posting this information on William Godfrey's work with 'Ross Rambler'. It appears he didn't have a problem using this Rosa laxa genotype as a pistillate parent. I think it's important to point out that the source of 'Ross Rambler' was likely a few thousand kilometres from where Dr...

Re: Hardy ramblers from R. laxa

Joe, "My Ross Rambler sets hips with one or two seeds per hip. But every single blossom that I pollinated last year failed. It seems like we'll have to use it as a pollen parent." As you may know, It was Dr. Giffith Buck who first wrote that Rosa laxa doesn't accept foreign pollen easily. That is al...

Re: Stanwell Perpetual

Percy Wright's statement that 'Ross Rambler' (Rosa laxa) repeats better than Rosa rugosa is definitely not true. Especially, when compared to 'Schneezwerg'. He was quite capable of hyperbole when it came to writing about roses he was excited about. For example, his own 'Hazeldean' and 'Ross Rambler'...

Roots - the neglected part of breeding roses

The focus of rose breeding, of course, has been on the development of attractive flowers. In recent years, breeders have devoted more attention to developing disease resistant shrubs. There is now more emphasis on having shrubs with good architecture and attractive foliage. But very little attention...

Morden Centennial X John Davis.jpg Andre, I'm surprised you would state 'Morden Centennial' is problematic to use in a breeding program because of its "thorns." That's not my experience at all. I never give it a thought I'll have a problem in this respect, and I never have had any. Perhaps it's the...

Re: 'Morden Centennial'

I would have liked to have seen more work crossing the Parkland roses with the Explorer Rosa kordesii ones. I know Morden used 'Frontenac' extensively with Parkland breeding lines and was successful with it. But it's not a typical Rosa kordesii rose in its growth habit and percentage of Rosa kordesi...

If you want pollen of these three cultivars next spring, let me know. I'll need a mailing address, of course.

Anyone else?

Re: 'Morden Centennial'

'Morden Centennial' is widely grown in Canadian Zone 2/3 climates, and I've grown several shrubs of it over a period of many years. I've never seen any disease problems, nor in the seedlings I've developed from it. Good to know that apparently its doesn't do as well in at least some warmer climates....

'Morden Centennial'

In my opinion, 'Morden Centennial' is the best all round Parkland rose. The shrub has good cold hardiness (excellent crown hardiness in Zone 3) and the large, double, medium pink, fragrant flowers repeat very well, if good nutrition and moisture is supplied to it. Better quality and performance than...
