This lovely ground cover isn't really hardy in my zone( 8a). Hard frost will kill most of it, although small pieces might and often do survive and the plant then regrows from them the next season.
Last winter I protected it with a thin frost-protection cloth mounted on a few thin bamboo sticks I had bent into bows over the plant. I took it off on longer periods of little or no frost. This worked wonders. The whole plant has survived very well and even looks very healthy and happy in nearly full shade, where I had planted it last year, and it has now spread to more than 5 times its original size. This looks better than a lawn in a shady location!
I love how it twines itself among other shade loving plants. It looks so much better than just bare soil! :)
I'm not sure how I will do it next winter when the plant will have spread much farther. I think protecting a few patches here and there, from where it can regrow, will do the trick..
It loves humid soil, but can withstand drought when planted in humus-rich soil in the shade.
