Ciliaria austromontana (Wiegand) W.A.Weber

Family: Saxifrage family (Saxifragaceae)

Habitat: Montane to lower alpine, rock ledges and forest floors

The flowers have white petals dotted with orange and red spots. Tiny awl shaped leaves form dense mats. It blooms from June to August.

The tiny leaves of dotted Saxifrage form a moss-like mat, cascading over the edge of rocks.  Three to six inch flower stems bear few to many flowers depending on growing conditions.  Red, orange, and yellow dots ornament the interior of the petals. This is such a beautiful, delicate plant that it begs for you to get down on your knees for a look  --  and you need a hand lens to really see the WOW of the flowers.
