Those are large leaves for a rose. An unusually bright shade of green, too. The flower coloration reminds me of the hybrid musk Felicia, but the foliage seems unlike most rose foliage I've seen. The coloration and the roundness of the leaves is suggestive of rugosa lineage. The distinctive smoothness and subtle wrinkling I've seen on Mountbatten, if I remember correctly. If I had to hazard a guess I might say
"Morgengruss." But I'm mostly clueless, too.
