My 2nd year with this rose and I've still to detect any fragrance. I also find it has a a very poor re-bloom, just one decent show, June to July then as of writing this it has given me a handful of blooms over several weeks since the end of the first flush. Did the same in its first year but I thought it would improve as it got established.

Perhaps Boscobel performs quite differently in different zones? I'm in Maine zone 5a, and of my 9 rose bushes, I find the smell of Boscobel to be the best of all of them. In my garden, the smell is just as strong as Princess Alexandra of Kent, and stronger (for me) than Crown Princess Margareta. I get consistent blooms from Boscobel as well. Even though the temps have been getting into the 30s at night (in October), Boscobel still has a few open flowers and buds, while most of my other rose bushes are just about done for the season.

How large does 'Boscobel' grow for you? I am also in zone 5, upstate NY, and am about to give up on Austin roses. For me, while they do survive winters, they never put out more than a few canes each season.

This summer was my 2nd season with Boscobel, and it's about 2.5-3 ft tall x 3 ft wide, so still pretty modest. I bought Boscobel in summer 2021 at a local garden center in a 2.5 gallon pot. I don't know if it's own root or grafted, but my guess is that it's grafted. I winter-protect my DA roses with rose collars filled up with soil, tie together the canes that extend above the rose collar with twine, then wrap the canes that are tied together in row cover and stuff some leaves into the row cover wrapping for extra insulation. I have no idea if that helps the bushes bloom in the summer, but it does help them get through winter without too much cane loss -- especially because I get a ton of wind where I am. During the growing season, I fertilize with a fish fertilizer to start, then rose-tone when I see buds forming, and then another round of rose-tone or another fertilizer I have on hand in August. I also add a layer of compost to the soil once in May and once in September/October. My only observation about blooming is that I've noticed that roses really don't do well for me unless they get full sun.
