Re: Spring Observations

Joe, Sorry to hear of your bad luck with the spray. Maybe the folks at the local golf course can recommend something. Twenty years ago, I could spray Roundup at the base of my shrubs around the time the grass was 3 inches high and before the leaves emerged. It worked well by killing the grass withou...

I have never seen hips with seeds on 'Agnes'. It tries to form them but there is only fluff inside.

Your Darlow's Enigma seeds may have larvae from the rose seed wasp Megastigmus aculeatus nigra which was introduced as a biological control of Rosa multiflora. We have its near relative megastigmus aculeatus in Alberta. I found larvae in every seed of some crosses. :(

Dr. Parminderjit Sandhu, the Canadian scientist in charge of rose breeding at Vineland Research and Innovation Centre, was scheduled to present the lecture. She has resigned from Vineland effective February 28th, 2018 due to health reasons.

World Federation Rose Societies conference - Copenhagen

I am wondering if anyone from this list will be attending the conference and will any of you visit the Sangerhausen rose garden afterward?
It seems there might be an opportunity to meet some of you in person rather than via the internet.

I am interested in learning if your crosses with R. acicularis eventually are subject to rust? Or is rust even a problem where you are?

Naturally, the link to the disease Appendix is not working. Perhaps someone else has a copy of it.

Wonderful crosses and wonderful pictures. I really like RR 3 x Louise Bugnet. How does it do on very hot days?

Re: Origins of Yellow John Davies

Last I heard, "Terry's Yellow" is being trialed somewhere in Canada thus there won't be a listing on HMF until the trial ends. Perhaps Terry will post and let us know how things are progressing.

Re: The Feasibility Study on the Prediction of Ploidy Levels

Thanks for the link Henry. I regularly check pollen diameter of roses intended for hybridizing. Sometimes the pollen sizes are fairly consistent and the measurements predict the ploidy easily. Other times the size of pollen grains are highly variable and the ploidy isn't obvious. I suspect it would ...

That is a pretty seedling. I wouldn't have expected a white blossom. Thanks for putting up the picture.

Re: Ross Rambler #4

Joe, every spring when my 9 foot Ross Rambler #4 is covered in blossoms exuding a strong perfume that can be detected from ten feet away, I think to myself there should be something I can do with this rose. So far, I haven't had much success. Good luck with your experiments!

Re: Species-Modern Crosses

My first thought was Percy Wright's 'Augusta'. Weak necked floppy blossoms, long bloom period, no hips, fragrant. But it is unlikely any nursery is propagating or selling it. Can you tell us the name of the nursery you purchased it from and in which province? The possibilities would be narrowed a lo...
