34 Alpine Plants. 
Ceratostigma Polhilli (Hab. ?). 
This shrubby species does best on a well- 
drained, sunny slope facing south-west, and well 
sheltered from the north, in a deep soil of loam and 
sand in equal proportions. The position indicated is 
chosen so that the woolly stems may be well ripened 
in summer. 
Chimephylla maculata (N. America). 
Plant on a well-drained slope facing south-west, 
and well sheltered from the north, in equal parts of 
peat, leaf-mould, and loam. In autumn top-dress 
among the twigs with a little sand and leaf-mould. 
Chrysanthemum alpinum (Europe). 
Of very easy culture, and useful for the Alpine 
garden. It likes a well-drained south position on a 
sloping bank, in a compost of sand and loam in equal 
proportions. This is a plant which often gets lost, 
though a little care in top-dressing once a year in the 
early spring would save it. Like Aster alpinus, it 
grows out of the ground, and when the dry winds 
come all the young roots perish. When the top- 
dressing is put on, the plant should be pressed well 
back into the earth, so as to make it firm. 
Claytonia sibirica (N. Asia and America). 
A plant suitable to be grown in a half-wild place 
among ferns, by the edges of paths through the 
rockery, where its running habit and profuse seeding 
will not matter, requiring, under any circumstances, 
a half-shady place either on a bank or on the flat, in 
any aspect and in ordinary garden loam.
