Fedco Seeds in Clinton, Maine calls this an "Orange-Honey" color, moderately fragrant, repeat bloomer. Says "Growing well and showing good hardiness in Zone 4 as a shrub with only some dieback to prune out after very cold winters." (also notes it's a climber in warmer zones). Picture shows very apricot/orange blooms.
High country roses calls it 'A good repeat bloomer', which suggests to my interpretation more repeat than what is hinted here. Can anyone comment on that? Is the foliage actually fragrant like the references mention? I find that surprising given the fact it does not appear to have all that much eglanteria blood. Certainly less than 50% if my math is not dumb. I've heard it's a hard trait to pass on.
The question is how strongly its seedlings express the genes for the foliage scent. It seems like the genetic trait has to be reintroduced through several generations in order to demonstrate itself in its descendents.
I wonder if backcrossing and clever hybridizing could create a truly continuous flowering sweetbriar.
