Robert sent me some cuttings of ‘CHXGLPE’ that I have rooting right now. It should be interesting to see if any disease resistance is inheritated. They look good so far.
would going back to ‘International Herald Tribune’ instead of ebb tide and midnight blue get you better disease resistance?
Patrick
I doubt it.
Patrick, have you had disease troubles with ET or MB?
Yes George I have. But down here on the Gulf Coast there are very few which do not have disease. I believe Ebb Tide might be a bit more disease resistant than Midnight blue here for me but still gets some blackspot. I have one bed which I do not spray and these stay Mostly clean. Darlow’s Enigma, Carefree Sunshine, Home Run, Carefree Marvel, Frontenac, Ovey(Darlow’s Enigma X Lynnie), Basyn’e Purple, Sunny K.O., Pretty Lady, Baby Love and one that I got from seeds from Henry, R. Acicularis X (Hansa X OP) X OP X OP.

Is ‘Hot Cocoa’ a good source of dark orange (to mix with smoky purples)?
I started playing with Cardinal Hume before I had access to Midnight Blue.
I had CH here as I was using it for rootstock at the time. It turned out to be surprisingly fertile.
I learned some interesting things about it. For example, it’s more accepting of diploid pollens than most. For that reason, like ‘Joycie’, and others it can be used as a bridge. Of course it’s not unique in this regard.
I put it with some of the most disease resistant stuff I had to work with at the time and rationalized I could select out what I was looking for and meld the result with things coming out of Midnight Blue, etc. That’s what I have done.
Jeff that was one of the things I had in mind when I created the CHXGLPE cross.
If I didn’t have so many things going on here I would have used CHXGLPE with Midnight Blue and others to hopefully create a saturated, hardier, disease resistant Shrub rose.
The new twist is incorporating glauca and pendulina into the mix.
I’d love to hear how something like that would work out.
Hot Cocoa would probably be fun.
I’m not big on older floribundas due to the disease issues, but Orangeade would be an interesting mix, too. It is found in the lineage of Brown Velvet, though, which is probably superior if you can breed out the mile long peduncles it has.
‘Brown Velvet’, was a mildew magnet here to the point that I couldn’t bring myself to use it.
Yes, something like Hot Cocoa will do the job 
That’s too bad, Robert. It is the most beautiful, along with Singing in the Rain, arrangement rose I have ever grown. The color is so rich indoors that it looks edible, lol. Hot Cocoa, despite being a superior plant, definitely does not induce even a similar feel. A plant with Brown Velvet’s romantic feel combined with Hot Cocoa’s health would be nice.
Yes Jadae, I kept ‘Brown Velvet’ for several years. It was a lovely plant except for the mildew. It flushed beautiful glossy new growth every Spring and within weeks it would be coated with gray. Here it never got those deep chocolate tones I see in photos. I finally shovel pruned it.
‘Singin in the Rain’ never mildewed here and was quite fertile in both directions.
‘Hot Cocoa’ also never mildewed here. Offspring are sometimes somewhat susceptible to mildew when young but seem to outgrow it over time. HC produced a fair number of singles and semi-doubles depending on what it was married to.
There was something about HC that just didn’t appeal to me. I only kept it one season. I think maybe the stiff growth habit and abundant prickles turned me off to it. The foliage was nice.
I plan on trying Cinco De Mayo next year just to see what it can produce.
Patrick
Yeah, Hot Cocoa feels very sterile to me. It isnt a very romantic rose whatsoever, but I believe it has a lot of breeding potential.
Hot Cocoa definitely throws burnt oranges that ‘blue’. The ‘flower within a flower’ mutation that it has is interesting and perhaps contributes to its reputation of being sterile.

Jon, is the picture above of ‘Hot Cocoa’ x self?
Jon, could give more details about the ‘flower within a flower’ mutation in Hot Cocoa? I don’t recall seeing a center like that in Hot Cocoa. Did the bud-like structure in the center of the seedling open to produce a new bloom?
That is a repeated problem in descendants of Silver Jubilee.
Is this central flower mutation what is referred to as a ‘vegetative centre’?
Yup. One is lucky to get seed from one of those. I have done it with limited success. It is mostly all mechanical error inside when that happens =/
