Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph of FIG. 1 shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, a typical specimen of the new variety. The rose plant of the new variety was approximately three years of age and was observed during May 2019 while growing on its own roots and growing outdoors at Cochranville, Pa., U.S.A.

(2) FIG. 1illustrates a specimen a plant with open blossoms.
