Alpine Rock Garden
Part 2

23. Saxifrage Garden
This garden is a taxonomic collection of the genus Saxifrage. Some of the most spectacular alpine plants in the world, these plants are found throughout the temperate Northern Hemisphere and into South America. There are 480 known species many of which are alpines that form spectacular evergreen domes or mats which thrive in rock gardens. The Saxifrage Society is a British society devoted to the genus and has a very informative web page with information and publications available.


Saxifraga oppositifolia


Saxifragia bertolonii


Saxifraga sempervivum

Our collections boast some 100 taxa, some species and many cultivated varieties. Among the most spectacular are Saxifraga grisebachii, S. sempervivum and S. valdensis, with their silver encrusted leaves and tight rosettes. Closer to the waterfall mossy types fills the crevices between the boulders including Saxifraga caespitosa and many cultivated varieties such as the showy red Saxifraga 'Garnet'.

24. Rocky Mountain Alpine Garden
This spectacular, north facing wall of quartizite boulders is home to a large part of our collection of Rocky Mountain alpine plants. In the deep vertical crevices in the walls cliff dwellers such as Telesonix jamesii and Heuchera halli cling to the rocky soil and flowers of Lewisia tweedyi thrive. The amazing woolly head of the Rocky Mountain thistle, Cirsium scopulorum caused a stir in mid summer emerging from between the rocks. Many shrubby penstemon flourish on the well drained soils with Penstemon rupicola growing alongside P. davidsonii ssp menziesii and P. fruticosus ssp serratus. The dark crevices provide a home for Linnaea borealis, the delicate twinflower, and Rocky Mountain clematis, Clematis columbiana var tenuiloba.


Penstemon hallii


Lewisia tweedyi

At the base of the wall, mat and cushion plants of the alpine tundra spread alongside the pathway, interrupted by the large upright heads of the alpine sunflower, Hymonoxy grandiflora, better know as 'Old Man of the Mountains'. Here many of the alpine phlox such as P.condenstata and P.hendersonii grow with Oxyria dygina, Alpine sorrel and Phacelia sericea or Purple fringe.
