Aquarell has been acceptably healthy in my no-spray garden in the past few years; it did get some blackspot in late summer and it shed a few leaves, but better than the average hybrid tea. Flower quantity is good, but repeat is not that frequent; it tends to produce a huge flush in spring and then occasional blooms here and there. Flowers are often in small clusters. Scent is strong and consistent, but quite unrefined in my opinion (basic citrus-fruity scent). It is quite vigorous and sends up frequent basals, even though it remains compact and about 75cm in height. Quite thorny and upright, but a bit better shrub shape than the average HT. When cut, its flowers look good and last about 5 days (more in the winter).

I believe this variety may well be some kind of hybrid rugosa (probably through Rugelda, as the blooms look very similar to Aquarell's. Augusta Luise's parentage is undisclosed, but I guess it could be Rugelda x some Hybrid tea); young foliage is deeply serrated, much more so than the usual HTs

Seems not to be a fast grower
the first 2 blooms does not have much fragrance...
still waiting
