I have a spot for a Tiger Eyes Sumac (Rhus typhina \'Bailtiger\') but am not sure if the plant I\'m buying is a tree or a shrub. Online nurseries identify it as both, and some state the growth as up to 6\' x 6\', but others as up to 8-10\' x 10-12\'. I would prefer something with more or a tree habit with a visible trunk at the bottom and spreading on top.

How do I tell what I\'m getting is a tree vs. a shrub? Or is it all the same, just depending on how you prune it? I\'ve attached an example of each.
