Dax, in the passed years I also found several white- and yellow variegated sports in Thuja occidentalis and Thuja plicata cultivars.
To get them rooted wasn't the propblem, but sooner or later all reverted back to green.
I hope your's will be stable, good luck!

I'll wait until next-spring and send them off to Frank since he roots hundreds or thousands of Thuja's every year using mist benches. It's much smarter for me to wait.

This one is rooted well. I rooted it winter 2012 from softwood during winter. It's a Green Giant sport that Frank found on one of his plants.
