May we call special attention to the offer of the eight Tried-and-True Rock-Plants pictured and described below. 
Tried-and-True Rock-Plants 
Aster, Mauve Cushion 
Arabis alpina. An excellent, 
prostrate plant from which 
short-stemmed clusters of daz¬ 
zling white flowers ascend 6 to 
8 inches high, making a showy 
white mass of bloom of snowy 
purity. 
Aster, Mauve Cushion. This 
is a sturdy, tufted little plant 
which, in Autumn, suddenly 
bespangles itself with hundreds 
of pinkish flowery stars which 
completely cover the plant. 
Campanula garganica. A 
quick-growing, extremely de¬ 
pendable plant with small, holly- 
Iike foliage borne in compact 
tufts. In late Spring the plant 
spreads rapidly into a broad, 
wheel-like mass completely 
buried in a profusion of soft 
lavender, star-shaped flowers. 
Helianthemum, Fire Ball. 
This is a wiry little evergreen 
shrub with pretty, dull, gray- 
green foliage which is practi¬ 
cally evergreen throughout the 
year. Beginning in early Sum¬ 
mer it produces a dazzling 
mass of fiery little silk-petaled 
flowers which continue in 
bloom on and off throughout 
the entire season. 
Iberis sempervirens. Hardy 
Candytuft is an extremely 
useful half-shrubby plant. In 
Spring its thousands of tiny 
white flowers lie like belated 
snowdrifts caught among the 
rocks. It is one of the hardiest 
and most dependable rock- 
garden plants for any situation. 
Iris cristata. A charming 
little plant of spreading habit, 
scarcely more than 3 inches 
high, which bears unbelievably 
lovely light blue flowers that 
have all the grace and charm 
of dainty exotic orchids. It 
grows happily on any sunny, 
well-drained bank. 
Phlox subulata. A quick¬ 
growing, moss-like plant which 
creeps rapidly over bare ground 
and rocks, covering itself with 
myriads of enamel-like flowers 
in innumerable shades of pink 
in early Spring. 
Thymus Serpyllum lanu- 
ginosus. The woolly Thyme is 
a soft, velvety foliaged creeper, 
gray and downy throughout 
the Summer but exceedingly 
attractive in lavender and dull 
purple shades during the 
Winter. 
Thymus Serpyllum lanuginosus 
Phlox subulata
