This says yes, they do hybridize…

Nice tree.

Handsome. I just planted a tiny one to try to have a dependable fir -- my Manchurian fir is badly susceptible to frost damage from budding too early. Does A firma bud out early or later than most frosts?

Hmm, might be a good idea for me to try a Fraser (or Canaan) fir.

This site says Canaan fir is late to break bud and so it'd be a good choice for my frost pocket.

FWIW, my Abies pindrow is even earlier than my Abies firma. Fortunately, with the way the local microclimate usually pans out, it has only been burnt once since I planted it in 2010. The dead needles blackened and hung on the plant for a year, which was really ugly. But North American and European firs would be expected to break bud later, because of our more capricious climate. Asia's Siberian anticyclone means there's less chance of early warming in spring so their plants haven't adopted to pause like ours.
