Re propagation - the female plants seem to spread well through suckers, but what about the male (not spreading - how would a cutting work?). Would like to have a spot in the back yard, too, and can use the 3 (Star of Altai) shoots I presently have that are doing well.

And would the male pollinate any type of female? Am thinking about Buryatian plant (Baikal Ruby), since it supposedly is shorter & sweeter.
