What is Saxifraga Mossy


💧Dockonsou (Solitary Root Grass)'s Water Drop Poem:
“From a Single Root”


by Aqua

From a single root
I bloom gently

Even if no one notices
Listening to the sound of the wind
Gathering particles of light
I bloom today

――Just that alone,
I am living
my life with integrity🌿💧


Dokkon-sou (Orestrophos rupifraga)


Dokkon-sou (Orestrophos rupifraga) is a low-growing, subalpine, cold-hardy, deciduous broadleaf perennial native to China, belonging to the genus Orestrophos in the Saxifragaceae family.
In spring, it produces a panicle and blooms with small, five-petaled flowers ranging from white to pale pink, each about 1 cm in diameter.
Large, round leaves emerge at the same time as the flowers bloom.
