Abstract

A new and distinct variety of climbing rose plant is provided which forms in abundance on a substantially continuous basis attractive clusters of semi-double informal clear yellow blossoms having approximately ten petals on average. The new variety is a spontaneous mutation of unknown causation of the ‘Radsun’ variety (U.S. Plant Pat. No. 13,063). The climbing growth habit can be readily distinguished from the free-standing growth habit of the ‘Radsun’ variety. Vigorous vegetation is formed. The foliage is dense medium green with a satin finish. Excellent resistance to Black Spot is displayed. Attractive dense ornamentation in the form of foliage and blossoms is made possible when the new variety is grown on a support.
