CHOICE PLANTS FOR ROCK GARDENS 145 
propagation is not invariably satisfactory, as the torn roots 
are liable to rot instead of making new fibres. 
ERYTHRONIUM.—Whether grown in patches in sheltered 
nooks upon the rockery, in the slightly raised alpine bed, 
or in pots and pans to flower in the alpine house or frame, 
the Erythroniums are plants of un- 
common daintiness and charm. 
The first attraction is their prettily 
mottled foliage, and for this alone 
in the early months of the year the 
plant is well worth growing. The 
flowers are, however, delightful both 
on account of their quaint shape 
and their delicate tints. E. dens. 
canis. (Dog’s tooth) is procurable 
in several varieties and different 
colours, lilac, lavender, rosy pink, 
white, and purplish red are all 
pretty, and there are a few other less common species 
available. The roots are fleshy corms, and whenever a 
clump becomes overcrowded it may be carefully lifted 
when the foliage has ripened off, and the corms separated 
for replanting. Erythroniums enjoy plenty of water so long 
as their foliage is above ground, but should be kept 
comparatively dry during the dormant season. 
GALIUM.—Feathery, airy lightness is elegantly exem- 
plified by the Galiums which make slender growths clothed 
with light foliage, and bear tiny flowers, but bear them 
in such profusion that they appear when disturbed by the 
slightest breeze to be just a smoke-like or vaporous mass,
