ALPINE PLANTS. 37 
adapted for the edge of the bog. It will grow 
well in full sun if planted on a damp bottom. 
If on the dry side of the bog a little shade 
is required. WD. octopetala is a more sun- 
loving plant and does well on the south side 
of rockery in gritty loam and sand. J. ¢enella 
is better adapted for smaller rockeries 
and can be planted close to the path in 
shade; peat, loam, and grit in equal parts. 
EDRAIANTHUS or WAHLENBERGIA. This 
beautiful class of plants does not seem to 
make headway as they might do, considering 
they are all of comparatively easy culture. 
E. Pumilio and E. pumiliorum require to be 
planted in the fissures of rock-work facing full 
south, leaving a nice space behind, so that the 
young roots can be well protected. They are 
of a very tender, silky nature, and if ample space 
is left behind and filled in with grit and a little 
loam, the roots cling to the sides and gather 
all the moisture they require. Make very firm 
between the stones. Care must be taken to 
see that the soil does not get washed away 
from the plants and leave the roots loose ; 
compost: grit, loam, and sand in equal parts.
