Abstract

A new and distinct variety of Landscape Shrub Rose Plant is provided that abundantly and substantially continuously forms attractive bright pink double blossoms. Such blossom coloration can be distinguished from the bright red coloration of the parential ‘Radtko’ variety (U.S. Plant Pat. No. 16,202). A round and bushy growth habit is displayed. The ornamental green foliage displays a satiny finish and contrasts nicely with the blossom coloration. Excellent resistance to blackspot as well as very good winter hardiness have been observed.
