Saxifraga stolonifera make excellent Bonsai accent plants. I have two in my collection with one being in a Bonsai pot for the time being. This plant arrived in the spring of 2021. The other plant arrived June of 2021 in a small plastic square pot. This plant has runners all over it from the mother plant. The plant spreads by runners. Its a beautiful plant and I am excited to have a couple of them.

My first plant growing in a Chuck Iker pot. Notice the plant is starting to produce runners which will have new plants on them at some point.
My second plant that arrived about a week ago, notice all of the runners with new plants on them:
Michael Hagedorn has a very nice article on this plant for Bonsai purposes. You can read it here: Saxifrage as a Greek God.
