26 Alpine Plants. 
Asperula suberosa (Greece). 
Plant, facing full south, in sandy loam. In spring, 
and again in autumn, top-dress with sand and loam. 
Aster alpinus and its varieties (Europe and N, Asia). 
These plants are all of very easy culture in 
any ordinary garden soil, but care should be

early spring being the most suitable time. If this 
is not done the plants will grow right out of the 
ground, the stems becoming quite bare, and, in 
most cases, eventually breaking off under the 
stress of wind. By using the top-dressing this is 
prevented and they will keep satisfactory for vears. 
Astragalus alpinus (Northern and Arctic Regions). 
This species requires a very hot sunny place 
with plenty of stones and poor soil, in the pro- 
portion of two parts of stones to one of soil. 
Astragalus argenteus (Pyrenees). 
Plant in a well-drained position, facing full 
south, where it will be as dry as possible in 
winter, in deep loam and limestone. 
Astragalus Tragacantha, syn. Massiliensis (Mediterranean 
Region). 
This plant does well planted high up among 
rocks, wedged tightly, and kept as dry as 
possible, taking care to leave plenty of room 
behind for the tap-root to get well down. 
Atragene alpina, sce Clematis alpina. 
Aubrietia deltoidea, in var. (S. Europe). 
These well-known plants like a south aspect, 
and form pretty hanging draperies down rock-
