I wanted to share my thoughts on crimson knight for hybridizing since it doesnt come up often in the forum. Im in charleston south carolina and this one is very disease resistant here. It is one of my cleanest bushes, comparable to spice, peggy martin, plum perfect, queen of sweden, and the knock outs. It doesnt like to set hips, but i have seen hips on it before, just not from my intervention. It does produce a low number of anthers, and they are fuzzy. So when ive tried to collect pollen, itll explode into my container and get mopped up by the fuzzy bits so getting pollen can be tricky. I havenât been able to use it in hybridizing yet, but i feel like it has a lot of potential and flower power. It also has a good fragrance. I wouldnt consider it strong though. The petals scorch here when it is more dry in the high heat, but still remains beautiful.

I canât respect breeders that intentionally omit pedigree information about their work. It leaves a hole in the knowledge about a breeding line, and itâs only done to obfuscate what the breeder regards as âproprietaryâ information. Feh.
I donât care how good a rose is, I wonât use it in breeding if I know absolutely nothing about the roses that went into its making.
I think itâs a false premise that by hiding the pedigree of a rose, the breeder is somehow âprotectingâ their creation. Anyone can repeat a known cross and never find a similar rose among 100,000 seedlings. Hiding pedigree info is just selfish and does nothing to further the understanding of extremely important aspects of hybridization, like overcoming Blackspot susceptibility.
But donât let my opinion dissuade you from trying to employ it in breeding - itâs just an opinion.

Which âCrimson Knightâ is it; GRAnib or JACmered?, which sounds like a deeply personal and HUGELY INAPPROPRIATE question, but isnât.

That must be âGranibâ, a.k.a. Brindabella The Nightbird/Crimson Knight. Iâve had one for two seasons and it has been a slow starter so far, also a bit slow on the rebloom, and the flowers can crisp in the heat as already statedâbut it does have fairly healthy foliage.
Iâve grown âGrapplâ, a.k.a. Brindabella Pride/Purple Prince, some years longer and like it better. Itâs pretty healthy in this tough climate and very fragrant, and the fast-repeating flowers have held up relatively well in hot weather. It sets hips easily and the seeds germinate well. Iâve grown many seedlings from various crossings but still havenât found the perfect combo yet. Despite the slightly cryptic reported parentage, I suspect that it is really from âGrasuperâ a.k.a. Brindabella Touch of Pink crossed with âSomnipâ a.k.a. Blackberry Nip.

Itâs not just their breeding thatâs unclearâŚ
Itâs funny looking at their site on web archive and looking at some of their early âtigersâ
Based on comments on HMF they donât know where they got these roses either but itâs probably pretty obvious 
They seem more focused on branding than anything else.
oh look, even further back on their website
