I had 4 of the same brug (I think they were Frosty Pink, but definitely a pink Sauveolens). Two of them put out seeds, and I planted some last year. I ended up with 9 out of 12 surviving, and I planted those out into the garden today.

I know they don't self-pollinate, but if you have multiples of the same plant, will they pollinate each other? What are my chances of getting anything other than the same flower or white? I wouldn't mind a white, honestly, but it would be nice to get something different.
