ZITKALA—THORNLESS 
55 Years Work 
With Hardy 
Double Roses 
By Prof. Niels E. Hansen 
This is a brief summary of my work 
since 1891 in breeding hardy double 
roses: The first four years, 1891-95 were 
at lowa State College. The next 51 years 
at South Dakota State College... Many 
thousand roses have been grown and 
discarded. Only the best few named and 
propagated. They are all hardy without 
winter protection anywhere, far north in- 
to Canada. I have worked for thornless 
roses because that would be a great im- 
provement. But it is a very difficult job. 
The work will be continued by my son, 
Carl Andreas Hansen, and grandson, 
Paul Robert Hansen. It is like the relay 
race of ancient Greece, where the runner 
carried a flaming torch from city to city 
to a distant goal—to victory. 
The Hansen Formula for Better Roses 
is to combine the hardiness of the wild 
rose of our northwest prairies and Can- 
ada with the best large double roses of 
America, Europe and Asia. These experiments were part of my work in Horticulture, origi- 
nating hardy fruits, and as Agricultural Explorer for forty years in eight tours to many 
lands, seven of them to Russia. 
ZITKALA 
A rich red, highly fragrant, very 
double. The lavender pink of the 
wild rose is eliminated: it is 100 
per cent red. My best red so far. 
Thornless, except for a few thorns 
at the base of the main stem. 
Blooms all summer. 
TETONKAHA 
My first pink hybrid of our 
prairie rose of South Dakota. Very 
free blooming and fragrant. 25 to 
35 petals or more. 
LILLIAN GIBSON 
A beautiful, dazzling, very dou-* 
ble pink, and fragrant. Blooms 
freely throughout the summer. 
SIOUX BEAUTY 
A beautiful red of the Siberian 
Rosa Rugosa and the American 
Beauty Rose. Very fragrant. Up 
to 69 petals. ALIKA 
One of the best hardy double red roses | 
found in seven tours to Russia, including one 
from the capitol of Russia to Vladivostok. 
Richly fragrant. Alika merits wide popularity.
