Climbing rose plant named `JACarch`

A climber rose having a vigorous, arching, climbing habit of growth; healthy, dark green, glossy foliage; recurrent bloom; resistance to disease; and ability to survive in Zone 5 of the U.S.D.A. Cold Hardiness Map.

The present invention relates to a new and distinct variety of rose plant 
of the climber class which was originated by the inventor by crossing the 
variety KORbin, with the variety Prairie Fire. 
The primary objective of this breeding was to produce a new rose variety 
having the repeat flowering, healthy foliage, vigor and cold hardiness of 
the female parent combined with the cold hardiness, healthy foliage and 
arching climbing canes of the male parent. The objective was substantially 
achieved along with other desirable improvements as evidenced by the 
following unique combination of characteristics which are outstanding in 
the new variety and which distinguish it from its parents, as well as from 
all other varieties: 
1. Heavy production of flowers produced throughout the growing season; 
2. Long arching or climbing canes; 
3. Glossy, dark green, disease-resistant foliage; 
4. Excellent vigor; and 
5. Cold hardiness in Zone 5 of the U.S.D.A. Cold Hardiness Map as 
established at Boerner Botanical Gardens, Milwaukee, Wis. 
Asexual reproduction of this new variety by budding and hardwood cuttings, 
as performed at Wasco, Calif., shows that the foregoing characteristics 
and distinctions come true to form and are established and transmitted 
through succeeding propagations.
