It's on the Style Network, Episode 809 with the (obnoxious, gross) MILLION DOLLAR wedding couple (as they mentioned 5784937543 times UGH vom).
The flower wall was actually part of the other wedding (the lowly, non MILLION DOLLAR wedding) - Lara and Andres. The bride works for Nicole Miller and her personal style was totally adorable, btw. Oh and I really liked her centerpieces.
You guys should watch it if you can! You know they repeat those things over and over. :>
