Rosen-Tantau says the correct name for this rose is Aquarell (TANellqua).
The (provisional?) breeder code TANgustedV indicates that 'Aquarell' is a sport of TANgust ('Augusta Luise')
The breeder code TAN03997 actually points to 2003 as the breeding year, which might confirm that there are two Aquarells.
Participated in the 2012 Glasgow Trials.
