Some All-Canadian Roses
by Fred Blakeney, Victoria, B.C.
Mr. Percy Wright of Saskatoon, Sask., must be considered one of the foremost hybridizers of species and near species roses in North America. He has been working on these roses for many years, and knows the reactions of various hardy roses when crossed with species roses.
His objective has always been to produce worthwhile garden roses that are hardy enough to withstand the extremely low temperatures of the Prairies in winter. [...]
Here is a list of Mr. Wright's originations in chronological order of introduction:
1938 "Hansette" semi-double red.

Book  (1959)  Page(s) 300.  
 
Hansette Hansa x R. rubrifolia. Semi-double, extra good tone of red. Smaller flower than Hansa.

Hansette (Percy H. Wright; Hansa x R. rubrifolia) is a bushy little plant which produces its 3 inch rose-red double flowers profusely in June and scatteringly throught the summer. The foliage is rugose, dark green and persistent. 2½' x 2½'.

"HANSETTE* - Our hybrid between Hansa and R. rubrifolia. Semi-double red. Not particularly valuable in itself, but has the power to transmit freedom from violet tones and non-fading."

Rosa Suffulta as a Parent
Percy H. Wright
The earliest hybrid I made was produced by putting pollen of the single Suffulta on the pistils of the Rugosa Hybrid, Hansa, an extremely hardy and vigorous variety not well liked except where it is about the only choice in everblooming roses, on account of its rather violet color. From this cross numerous seeds are easily got, fifty to a hundred per hip, and nearly every flower catches. From my first cross I got Hansette, about intermediate between the two parents, but tending to be more like Hansa when thriving and when a full grown plant, and more like the wild parent when suffering from drought or just getting a start. The flower is small, red without violet tones, and possessing thirteen petals. It is fully fertile both ways, though its mother is probably a diploid and its sire is a tetraploid. Unfortunately it is as susceptible as is Hansa to root galls. It attains about three feet, is broad and bushy, and blooms earlier in the spring than either parent. It blooms but once, each parent having suppressed the type of everblooming shown by the other.
