This rose is prone to proliferation and is susceptible to mildew (in my conditions - USDA 7b, Vienna). Otherwise, nice fragrance and reliable repeat.

"SUMMARY OF THE INVENTION

The new variety of Rosa hybrida hybrid tea rose plant of the present invention was created during May 2008 at Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was the `ADAterhuit` variety (non-patented in the United States). The male parent (i.e., pollen parent) of the new variety was an unnamed seedling from a previous cross of an unnamed seedling and the `MACgenev` variety (non-patented in the United States).

The parentage can be summarized as follows:

`ADAterhuit` x (unnamed seedling x `MACgenev`)" -US PP31,603
