ALPINE PLANTS. 57 
side, and should be planted 3in. deep; the 
compost must not be pressed too hard above 
the bulb, as it should be left free to run in 
the soil. Under the above conditions success 
is almost certain. 
LINNA:A BOREALIS likes a shady place on the 
side of bog ; peat, loam, and sand; or on the 
north side of rockery near a path-side, where 
it can have attention. A top-dressing of leaf- 
mould and sand should be given once or twice 
a year, so that the young tendrils may root 
freely. Pegging down should be attended to, 
in case the wind loosens the shoots. A rather 
damp bottom suits it well. 
LINUM SALSOLOIDES. A most useful plant 
for dry, sunny fissures of rockwork ; full south. 
Plant tightly between stones. Gritty loam and 
leaf-mould—two parts grit, one part loam, one 
part sand—will suit it. Leave sufficient room 
for the plant to hang over the stone. 
LITHOSPERMUM GRAMINIFOLIUM. This plant 
requires a little limestone if possible. If no 
limestone is obtainable, use rough grit and 
strong, rough loam, with a little sand added. 
Plant in a sunny position. A good top-dressing 
of fine limestone and loam should be given
