Rose Hybridizers Association Forum

Philip, if I have learned anything from hybridising roses over the last 15ish years is that you listen to what other people say, think about it, consider it, and then try it anyway with that advice in mind because many of the obstacles can be environmental and once exposed to a different set of abio...

[attachment=1]OPlaevigata12.jpg[/attachment] [attachment=2]OPlaevigata5.jpg[/attachment] [attachment=0]OPlaevigata3.jpg[/attachment] [attachment=2]OPlaevigata5.jpg[/attachment] I have put laevigata onto Marie Van Houtte and got plenty of seed. I got one to germinate but it didn't make it to cotyledo...

There is a newish purple rose from the Kordes stable called 'Purple Glow' ( http://www.helpmefind.com/gardening/l.php?l=2.71592 ) that may be of some use. It has superior health compared to other purples I have grow but lacks the darkness of something like 'Ebb Tide'. It makes copious amounts of pol...

[attachment=1]TBxThereseBugnet7.jpg[/attachment] [attachment=1]TBxThereseBugnet7.jpg[/attachment] This one is 'Temple Bells' x 'Therese Bugnet'. Once flowering and excellent health... but does VERY poorly in my ground. 'Temple Bells' also does very badly in my ground. Strong and vigorous in a pot. I...

Certain rugosa hybrids seem to be better than others for disease resistance. The best I have found for my area (in Tasmania, Australia), is Dagmar Hastrup. This is an OP I kept from it that has essentially reverted to wild-type rugosa but which is very healthy (no disease). It also tends to make ver...

I tried growing it years ago with ideas of doing a 'Baby Love' recreation, because we don't have BL here in Australia. It failed to thrive here, declined, and disappeared. I would now go back to 'Nozomi' instead as it seems to make much better progeny and then you can miss that whole 'Bright Smile' ...

Rather than hijacking another thread I thought I'd start a new one on 'Purple Rain' for you, Phillip. It's a rose I have grown for quite a few years now and it really thrives on neglect (and I do mean total neglect) and has been 90% clean the entire time. It remains almost fully leafed out here in T...

Phillip, Paul Barden used foliolosa to develop lovely rich purples. I've often though 'Ann Endt' would work in a similar way: http://www.helpmefind.com/rose/l.php?l=2.62352.0

My Ann Endt x ? ( probably 'Madame Isaac Periere') seedling looks like this: http://www.helpmefind.com/rose/l.php?l=21.257318

Hoping to use it 'Ann Endt' again this season.

It depends what the parents are. I find the wider the cross the longer the wait and a lot of stuff involving Rugosa seems to take forever. I have two 'Laura Ford' x Rugosa 'Alba' seedlings that I have been waiting for about 6 years to flower because I want to create miniature rugosa. I just want the...

For those wondering about using 'Winter Sun'... for me, in a location where even the black spot gets black spot, it is terrible and completely defoliates... and it has an ugly growth habit to boot. It is fertile and makes enormous seed-filled hips that germinate easily but nothing good has ever come...

It's probably a little early to call for this seedling, I feel. I have had similar seedlings that seem to be small to begin with which take some extra time to get going and once they do they catch up with the others, more-or-less. Almost like they were trying to sort out their newly acquired genetic...

P.S. ... it's great to hear from you again :)

Yes, I have that one as well. It is not too bad health-wise but also doesn't come close to the current Chris Warner hybrid hulthemia for health and overall garden merit. It works well as a pollen parent and contrary to what I have read on here regarding the climber-like offspring of E4Y, I have foun...

SSC is very disease prone and so far I have struggled to get around this. It had very bad mildew shortly after I got it (potted) but this disappeared once put in the ground where the supply of water was more reliable. This gave way to black spot and both my plants completely defoliated. Don't laugh ...

I collected openly pollinated arkansana hips from a plant growing in the Tasmanian Arboreturm (http://www.tasmanianarboretum.org.au/). Since S. Akimoto & Y. Ueda (Cross- and self-compatibility in various species of the genus Rosa. Journal of Horticultural Science & Biotechnology (2001) 76 (4) 392-39...

Woodsii did not do well for me, however, it was very dry at the time and water stress may have also played a part in its demise. Rosa palustris, and roses containing palustris, are (so far) proving to be quite good. I also dabble in growing carnivorous plants (Drosera and Dionaea ), and know that re...

This one, based on the 2nd photo, looks to have a carolina influence, not multiflora as in 'Seven Sisters', however, other features such as habit, etc would help. Is it a rambler? and http://www.helpmefind.com/rose/l.php?l=21.283466 The foliage is fairly consistent with what I am seeing in 'Commande...

I have the exact opposite! My acidic soil (5.5) on deep red basaltic clay/loam over basalt bedrock tends to lock nutrients up and roses like Chinas, Noisettes, Teas, etc, really hate it here. Unless they are potted in soil augmented with chicken manure to lift the pH they usually dwindle and die. Th...

Happy New Year to all! I grow Honorine de Brabant now, and have done so for the last 10 years, and have read on here over the years about how it is not the cleanest rose and can pass on mildew susceptibility to its offspring... but to be honest... I haven't seen any of that. It can pass on its strip...
