In recent years the creation of improved "landscape friendly" shrubs for cold climates has become more of an aspect of my work. To that end, I made a cross in 2007 of 'Golden Angel' X 'John Davis'. I have noted that 'Golden Angel' has bred not only some very disease resistant varieties ('Apricot Twist' is nearly 100% immune to Blackspot and Mildew) but also has the potential for breeding cold climate yellows, seeing as its seed parent was the Brownell climber 'Golden Glow'.
Here is one of about 14 seedlings I obtained last year from this cross of 'Golden Angel' X 'John Davis'. In my wildest dreams I did not imagine getting a yellow as clear and strong as this. (Bloom is about 2/3 open. I will photograph it again later, and get a shot of the plant also) As was expected, this group did not bloom in their first year, as these types of seedlings tend not to have any juvenile remontancy. These first flowers are not large, about 2" across, but the plant appears to have superior architecture and the foliage is very beautiful, with a nearly species-like look: dark green, matte and a bluish sheen. There are two other yellows from this group so far and several still to bloom. This is very exciting as these may prove to be useful in the breeding of good yellow disease free shrubs for locations with harsh Winters.
Very busy day, so I can't go into any more detail. I hope to get another photo later today. Enjoy!
