It seems like most of my ideas about increasing winter hardyness revolves around hybrid spinosissimas. This summer, I plan to add 2 roses that I have placed, with a few others, at the center of my hybridizing plans.
Hazeldean and Beauty of Leafland, along with Suzanne, Applejack form a kind of core that I want to start with. 3 of these are hybrid spinosissimas.
I hope to find a little more about B of L and Hazeldean. Thinks like habit, flower size, fragrance petal counts. I am really curious about what first generation crosses from these rose may bring.
Initially, I want to use the pollen from these 4, on Prairie Harvest, Graham Thomas, Golden Glow firstly and then on all the 20+ other Buck roses I have.
Hazeldean is kind of a mystery to me. Paul O. had originally brought it up as a potential starting place for a hardy yellow climber. Its at the center of all my plans but I know little about it. There are few hybrids from it and I can find little information on it. I wonder if Morden is using it. I thought I remember it being said that it does not pass its disease resistance well. Are there other results from using it that people have not talked much about?
I have the same questions about Beauty of Leafland. To me, it is at least as interesting at Hazeldean yet I her no mention of it as having potential for creating interesting hybrids. Does it have problems as a parent? Does it produce poor pollen or seeds with low germination percentage?
Perhaps its 2 year period of time for seeds of these roses to germinate that has discouraged people from using them as seed parents. Perhaps its as simple as an availability issue. Its very hard to get them in the US.
Right now, my plans include using these hardy roses with climbers like Autumn Sunset and Golden Glow. Another is using them with Buck roses. I am adding Baby Love and hope to cross it with Applejack, BofL and Hazeldean.
Speaking of Baby Love, how winter hardy is it? Since it has been mentioned that is passes disease resistance well, I thought it would be a good rose to add. I want to cross it with Folksinger as well since it is prone to mildew.
There is room with these 4 for other roses. One possibility is j5. I currently have a struggling cutting of j5 that only has a 50/50 chance of making it to summer. I am really curious about this rose as there is even less info about it than Hazeldean. I wonder what is parents are and what its actual winter hardyness is.
What about Aicha? It has no offspring. Is it fertile?
There are some other roses that are hardy and I am not sure where to put them. Wasagaming for instance. This is a hardy rose but I am not sure that I want it at the core of my effors.
Just some more rambling. Any thoughts?
