Almost everything you say about a rose called Excellenz von Schubert is wrong! It is a purple Hybrid Musk, with a delicious heavy scent, not a deep pink Polyantha with no to mild fragrance. Gregg Lowery says: Long clusters of small, full, grape-purple to crimson flowers, sweetly scented, on a plant of moderate growth with burnished, olive-green foliage. A Lambertina of exceptional quality; the bright panicles of bloom make quite a show in the garden. He gives it four r's for repeat bloom, and three f's for fragrance, and lists it among the Hybrid Musks.
