Progress in Hardy Everblooming Roses

But what possibilities remain for the use of rugosa in the breeding of hardy everblooming roses? It would appear that if Rosa rugosa is first crossed with Rosa blanda, and then this hybrid is bred to Hybrid Teas of Floribundas, the dominance of rugosa's weak bud-stems and excessive thorniness is broken much more effectively than if repeated infusions are made with the tender roses to a similar degree of loss of hardiness.

The rose Therese Bugnet, which most of us regard as a Blanda Hybrid rather than a Rugosa Hybrid, is an example of the truth of the foregoing assertion. Its percentage of rugosa, however, is substantial, and it is to the rugosa element in its make-up that the fall blooming habit of the variety is due. The limited number of seedlings of Therese Bugnet raised to date suggests that the combination of good features achieved in it was due to an extremely rare and felicitous segregation, but this is no reason, of course, why the line should not be followed much further.

It's known, that the flowers of this rose smell like Rugosa Roses and cloves, but this year a distinct fragrance of blackberries is detectable very good.
A very nice combination of scents.

"I will send you my most satisfactory child. Thérese Bugnet. A lady in Calgary, wrote me that she pulled out all other roses under her parlor windows to replace them by Thérese B.
The parentage is:
Lac la Nonne x R. amblyotis (a single red rose from Siberia) - recrossed again with R. rugosa fl. pl. - and another cross with pollen of Betty Bland.
You can easily mutiply it by cuttings and layering. I does not sucker at all - at least in my clay soil. And you have my permission to sell it. Being now past 71 I am quite free from money-making ambitions.
By using it as mother parent (or pollen parent? I've not tried this) you have a chance of better progeny. The everblooming quality is very prominent, beginning some years before the natives, until frost."
