10 ALPINE PLANTS. 
land). These plants do not make the head- 
way in gardens that one would like to see. 
They are of very easy culture and purely 
rock, sun-loving plants, and should be grown 
between stones on an elevated place looking 
full south in a mixture of rough limestone and 
loam in equal parts. Pressure should be 
brought to bear on the roots by pressing the 
stones close together, so as to make the plant 
as firm as possible, leaving plenty of room 
for the roots to descend. 
ALLIUM ACUTANGULUM (Western Swittzer- 
land and Pyrenees) and PEDEMONTANUM are 
both limestone-loving plants. Where lime- 
stone cannot be had, strong clayey soil should 
be mixed with grit-stone. If planted on the 
level part of the rock garden, the place should 
be well drained. A full south position suits 
them best. There are several other species 
worth growing on the rockery which do well 
in any ordinary soil and in any aspect. 
ALSINE ROSANI, A. BIFLORA (a rare species), 
TENUIFOLIA, &c. These belong chiefly to 
Switzerland and the Pyrenees, and require a 
light sandy, gritty soil, in sunny positions, in 
crevices of rockwork or a dry sandy bank.
