belongs to Saxifragaceae, where it is places among other genus as for
Astilbe, Heuchera and Rodgersia.
In the genus Saxifraga there are 300 to 400 species and an unnamed numbers
The name Saxifraga is compound of the Latin saxum, which means stone, and frangere,
which means to break.
The name of the plant refer to the place where it grows, which is narrow
rock clefts and crevices, and it gives an illusion of that the plant splits
It's a wonderful plant for the rock garden, not only because of the fine
hillocks, but also because it, depending on weather, start blooming as early
as in February of Marts.
grows in cool mountain areas in Europe, Himalaya,
China, N. America, N. Africa and in the Andes.
Plants who grows in mountains are normally cowered with snow through
the winter, why they can have a little problems with our wet winter, where
it changes between frost and thaw. Eventually you can cower with a plate to
get the worse moisture away.
The genus includes a lot of different plants. Some are quick growing and
has big vigorous, green leaves and big flowers,
while others are very slowly growing and has small grey-green succulent
The small plants can have hard rosettes or mossy leaves.
Our interest especially gather to the small hard hillocks-made plants,
the so called Porphyrion.
The following description only treats the Porphyrion (but there
are other Saxifraga who likes the same conditions).
The plants in this group, have small leaves, and they makes
hard rosettes, which by the time again makes hillocks as hard as stone.
The leaves margin often are filled with grey or white lime tooth.
The flowers are often big in proportion to the size of the rosettes. The
flowers are white, yellow, peach, orange or different shades of red, from
pink to strong red.
Saxifraga grows in barren soil on limestone, with a good drainage
(scree is fine)) and on the north site of a stone, so they are a little
protected from the strong sun.
The more barren soil the harder rosette.
Propagation by dividing or by seed.
