22 Alpine Plants. 
Arabis androsace (Asia Minor). 
This plant does well in the chinks of rockwork 
facing full south, where it will be fairly dry in winter ; 
in sandy loam. 
Arabis Halleri (Carinthia). 
This species requires a little limestone mixed 
with the loam. 
Arabis: Remaining kinds. 
These all do well in any sunny place in sandy 
loam. 
Arctostaphylos alpina (Alps and Pyrenees). 
This is a very useful plant for the edge of the 
small bog-garden. It likes shade, but no water 
must stand near the roots in winter. Plant firmly 
in equal parts of peat, leaf-mould and loam. Top- 
dress in autumn. Care should be taken to peg down 
the shoots, so as to prevent the wind from breaking 
them off, as they are very brittle. 
Arctostaphylos: Other species. 
Of much easier culture, doing well on the shady 
side of the rockery in sandy loam and peat. These 
do not require pegging down, as they root well from 
layers. 
Arenaria aculeata (Alps.) 
Plant on a dry, sunny part of the rockery, 
wedged tightly between two pieces of sandstone, as 
it must be dry in winter. With the necessary 
difference in the stone used, it does well in a similar 
position to Acantholimon venustum.
