I2 ALPINE PLANTS. 
seen in gardens, should have a _ place on 
every rockery where rare Alpines are grown. 
It is no doubt rather difficult to grow unless 
in the right position and soil; use a compost 
of leaf-mould, white sand, and peat (equal 
proportions). Make the place 18in. deep, 
with good drainage, in a partially shady 
spot; mix the compost well together before 
planting ; make the plants perfectly firm, and 
after the plant is in its home cover the sur- 
face with fine white sand, and give a good 
watering, so as to settle the sand well among 
the shoots. Great care must be taken to 
top-dress twice a year—spring and autumn— 
with sand, leaf-mould, and a little fine peat. 
Spread out the young growths over the 
surface, and peg them down, then add the 
above compost, cover the young growths to 
within 2in. or 3in. of their tips, and when 
this is done give a good watering as before, 
and the young roots will soon make headway 
among the freshly-added soil, and make pro- 
vision for the following season’s blooms. 
A. tetragona requires more shade; but a
