Has anyone planted alpine plants like Saxifraga on the margins by essentially building a miniature rock garden? I just received one saxifraga today, and while it's a great plant, in clay it is as good as death after a month, it can't handle wet soil, at least that has been my experience. And in rocks it just looks natural, my natural idea of course is just creating a little void space held by rocks on the margins, plant the saxifraga in between and fill in with gravel. This is what they do typically anyway, but I am wondering if anyone's done this on the pond margins.
