Small can be beautiful in the world of Saxifraga as can be seen with this Saxifraga Cranbourne one of the Kabschias series. This hybrid has a flat cushion bearing many rose pink flowers.
Normally Saxifraga suendermannii has a solitary white flower but x kellever has these pink flowers. The hybridisation of Saxifraga is one of the pleasures of this plant.
Saxifraga griesbackii from Englerias section has lime encrusted rosettes with tall arching sprays of pink flowers. The flower stalk is covered in deep red glandualr hairs show above. They look good over a long period whilst the inflorescence is growing and opening.
I have arrived late to the pleasures of Saxifraga but to see the range of plants I have been missing I looked at the Rock Garden Society of North America
