R. Brunonii/ Himalayan musk rose

I see quite few posts about Brunonii when searching on the forum. I recently bought one and its vigour is astounding, with each new cane on it growing almost 5 cm a day. I’m at about 20 pollinations with it as seed parent and I’d like to hear what people’s experience with it is, especially in terms of stratification.

I read in some places that it doesn’t do too well in drought conditions. The articles that I read this in aren’t clear if this is in terms of other species roses or modern roses however. Has anyone found this to be true?
