Based on the info on Tera Nova's site, it's ideal for the deep south with high humidity. The site lists three species in the breeding. The villosa heuchera is native to the southeast, so my guess is that even if it is listed as good for northern gardens, it may not do well without the humidity needed during the summer season. Of course, that is just a guess on my part.
Even tho' I like the photos, I'd be hesitant to try it in my climate which has very low humidity during the summer months.
