12 Alpine Plants. 
Linum narbonense (5S. Europe). 
This plant is fine on a large rockery under 
similar treatment to the preceding species. 
Linum salsoloides (S.W. Europe). 
A useful plant for dry, sunny fissures of rock- 
work facing full south. Plant tightly between stones, 
in two parts of grit to one part of loam and one of sand. 
The plant should be so placed that sufficient room is 
left for it to hang freely over the stone in front of it. 
Lippia nodiflora, syn. repens (Tropics). 
Useful for covering a surface under-planted with 
bulbs. Plant in partial shade on the flat facing west, 
in loam, leaf-mould, and sand, in equal proportions. 
In early spring top-dress with a little fine leaf-mould 
and sand, as the rhizomes creep on the surface. 
Lithospermum canescens (N.W. America). 
Plant in a well-drained place in partial shade on 
the flat facing south-west, in a mixture of equal parts 
of strong, rough loam, leaf-mould, and sand at least 
12in. deep. In spring, as soon as the young shoots 
begin to appear, these should be protected against 
snails and slugs by a sprinkling of fine steel-turnings 
around the collar of the plant. When active growth 
begins, give abundance of water until the plant has 
flowered. 
Lithospermum Gastoni (W. Pyrenees). 
Requires a similar place to Moltkia graminifolia, 
but does better if planted between stones. Limestone 
suits it best. It should have plenty of depth of earth, 
and the compost should be made as rough as possible.
