ROCK GARDEN PLANTS 
Rock Gardening enjoys great popularity at the present time and it surely is a very 
interesting pastime. Flower lovers have found that a small, simple Rock Garden can 
be just as delightful as an elaborate one. Out of an almost limitless list of plants 
suitable for the Rock Garden we have selected the following: 
PHLOX-AMOENA. Dwarf growing plant 
which spreads over rocks forming a dense 
mat which is covered with pink flowers 
during April and May. Foliage is deep 
green, it is attractive even when not 
blooming. 
PHLOX-SUBLATA. Just the plant to 
use in cemetery work as it is in full bloom 
on Decoration Day. The plant is so en¬ 
tirely covered with delicate pink star-like 
flowers during full bloom that the light 
green moss-like foliage is entirely hidden. 
GYPSOPHILIA-REPENS . Dwarf growing 
form of the popular Baby’s Breath. Light 
green foliage. Has white single flowers 
covering plant during June and July. 
VERONICA-SPICATA. Erect growing 
plant bearing beautiful blue flowers in 
June and July on spikes which protrude 
through the dark green foliage. Height 
1 % ft. 
DIANTHUS-DELTOIDES. One of the de¬ 
lightful pinks bearing red or pink flowers, 
has dark green foliage. In height 1 ft. 
Blooms in May and June. 
DIANTHUS-PLUMARIUS, or Grass Pinks, 
the kind our grandmothers used to raise. 
They make a fine border plant and the 
flowers which are very fragrant may be 
used to decorate the table. The flowers 
vary in color but generally have a white 
border and pink center. 
FESTUCA-GLAUCA (Blue Fescue). This 
is one of the most unique rock plants that 
grows. This little tufted grass has silvery 
blue foliage and grows only 10 inches tall. 
The plants are evergreen. 
SATUREIA (Calamintlia) ALPINA. 
Small green-leaved foliage, bearing small 
rosy-purple flowers. Grows 8 in. tall. 
CERASTIUM-TOMENTOSUM. (Snow in 
Summer). Low growing silver foliaged, 
dense growing plant, bearing myriads of 
small white flowers in June. 
CESRASTIUM-ARVENSE. Low growing, 
green-leaved plant, which stands hot, dry 
weather. Slow spreading variety. 
SEMPERVIVUM—Hen & Chickens. Pale 
green leaves surrounded by small rosette 
like offshoots. Stands hot, dry weather 
better than any other variety and is used 
in flower boxes for decorative purposes. 
SEDUM STAHLl. One of the best sedums. 
Slow spreading. Beautiful green in sum¬ 
mer and red in winter, has small white 
flowers on short stems. 
SEDUM FOSTORIUM. Blue-green, slow- 
spreading sedum; very different from oth¬ 
er varieties. 
SEDUM-SARMANTOSUM. Fast-growing, 
having light green foliage and yellow 
flowers. 
SEDUM, Acre. Yellow blooms from May 
to July. Slowly spreading plants with at¬ 
tractive deep green, fleshy, small leaves. 
SEDUM, Spurium Coccineum. Beautiful 
rosy crimson flowers during July and 
August. Of creeping habit; 6 inches. 
SEDUM, Album. A dwarf, spreading 
plant with thick, waxy foliage. Pure 
white flowers in July. 
SEDUM, Sexangulare. Very much like 
Sedum Acre, but with brown foliage. 
Vivid yellow flowers. 
THYME, Blue. Thyme of any variety is 
the most beautiful creeping plant that 
grows. It is the same color both winter 
and summer. It spreads slowly and is 
very hardy. If you do not have thyme 
in your rock garden you have omitted one 
of the most beautiful and outstanding 
rock plants. Blue thyme is used as a 
herb as well as a rock plant. The foliage 
is a decided blue color. 
THYME, White. Green foliage, having 
tiny white blossoms in July and August, 
otherwise same as Blue Thyme. 
THYME, Purple. Same as White Thyme, 
except it has purple flowers in place of 
white.
