Yea, it seems that it sprouts new ones rather than regrowing the cut ones. I wonder how my local nursery has a HUGE HUGE HUGE Canadian chokecherry tree that's a big ol' tree, but you never ever see sprouts down at the base. If it weren't for the flowers I'd dig the tree up, but it shades my one room SO nicely and is a super fast grower and the flowers smell SOOOOOOOOOO good in the spring. That room used to get 90+degs in the summer w/the AC on because it faces pure South & the sun would just beat the snot outta the window. The tree protects that room nicely so it doesn't get as hot now.
