Did you hear a deep voice intoning "I am that I am" and have a strong urge to take off your shoes and prostrate yourself before it??
Seriously,
For most of the year these plants are fairly non-discript but WOW! in the fall they are amazing! For best fall color plant them in full sun (no shade - at least up here in Michigan!) the more shade, the less striking will be their fall color.
I din't realize that they are classified as "invasive" but they are fast growing - the second link talks about their easy propogation by seed carried by birds, etc. Up here in MI, I guess the winters inhibit their growth somewhat though our neighbor has one that is easily 10 feet tall. Prune at will! (best in spring up here, anyway)
Here's are a couple of links for more information:

This one talks about it being invasive - especially in the south...
