I googled... very pretty.
While I can't tell you about this specific tree, I have had locally native aralia spinosa in pots for several years.
They have gorgeous leaves, incredible blooms, attracting masses of pollinators... and they root into the soil below, sending up children out into the garden.
Also... prone to having the pot blowing over.
10 foot high sounds about right...
I haven't tried cutting back, but have seen branching in this normally single stem plant, so... suspect it would grow back from being topped... but it would look funny.
Hmm.

Apparently, Japanese aralia is less of a single leader plant... Whack as much as you like.

Apparently the aralia spinosa is a showier plant...
