The Saxifrages 
The Saxifrages are an indispensable part 
of every rock garden, and rightly so, for 
their varied rosettes in green or grey, and 
delightful flowers, make them among the 
choicest of all rock plants. They have 
never become as popular as they should in 
this country, being all too often regarded 
as difficult, or even ungrowable. Such 
is far from the truth, at least for the 
northern states; the difficulty probably comes 
from trying to handle them as the Eng- 
lish do, in too sunny and dry exposures. 
Saxifrages are very shallow rooted and ex- 
tremely sensitive (in spite of their hard 
and enduring appearance) to heat and 
drought. Grow them in light shade and see; 
that they never dry out, and the problem is 
solved, at least for most species. 
The easiest from seed, germinating quick- 
ly and forming flowering plants in a single 
season are the beautiful Mossies. These 
make domes of rather open rosettes of much- 
slashed green leaves, over which on stems 
of 4 to 12 inches, are a profusion of cup- 
shaped flowers over half an inch across in 
late spring, varying in color from white 
through pink to fairly deep reds. Growing 
from seeds, the writer, has had no trouble 
and from a single packet the garden i9 
populated with a wealth of delightful and 
varied plants. These may not be as good 
as the named varieties in some respects, 
but they are an endless source of pleasure 
The Mossies seem to like a fairly rich 
soil such as suits many Primulas and a 
fair amount of shade, though an occasional 
seedling will prosper in the sun. 
The Encrusted types requires a_ gritty 
soil and fairly sharp drainage, but the es- 
sentials are light shade and moisture. These 
make compact rosettes of grey leaves, green- 
grey, blue-grey or just plain grey, with a, 
beading of silver along the edge of eachi 
leaf. This beading is made up of tiny pits 
containing lime, from which it would at 
once be deduced that the plants requird 
lime, but such is not the case, though most 
will be somewhat happier in a lime soil. In 
size the rosettes vary from %4 to 6 inches 
across, and quickly spread into fairly broad 
mats or humped domes. The leaves may be 
very narrow or fairly wide, straight or 
spoon-shaped. The flowers are plentiful on 
stems of 2 to 12 inches, pure white, white 
with red dots, pink or rarely yellow. This 
group hybridizes very freely and a packet will 
give quite a variety of types, regardless of 
the seed parent. 
The Kabschias are the choicest of this 
huge family, making very tiny rosettes of 
leaves quite varied in shape, and bearing one 
or more flowers on almost negligible stems. 
In many varieties the individual flowers are 
larger than the rosettes that produce them! 
The color range is extensive, from pure 
white through yellows and soft pinks to 
reds and purples. This group prosperq 
under the same conditions as the encrusted 
group, but being so much smaller and even 
more shallow-rooted, needs more careful 
attention. 
There are many other types of Saxifrage, 
extremely varied in appearance, but the ones 
mentioned above complete the choicest and 
best.
