The two planted are doing fine, but definitely grow and root less rapidly than Bowle’s blue variety I typically use. The two pots I didn’t get into window boxes got heeled in to large planter until I can get around to them. However, one went crispy and died completely a couple weeks later. I believe this is due to my not watering it and having the planter on my south facing patio. I put the one surviving pot into a shadier area and and trying to root a few clippings from it. So far, no success. Based on my experience, I’d say this variegated version is likely to be less invasive than all green cultivars and certainly less so than the species.
