CACTUS ROCK GARDENS— 
DISPLAY BEDS 
'Po test the success of a cactus 
bed is to .iudse of its ability to 
produce good normal growl h, 
flowering i)lants in their seasons 
and to ha\e these plants con¬ 
tinue through the years without 
loss. Considering the foregoing 
the most successful beds we 
have noted are those which are 
built uji entirely on top of the 
ground. Sustaining walls of 
rough flag stone are slightly 
burii'd. sidewise, following ir- 
regular lines around the outside 
of the bed and also leading into 
the center which is considerably 
elevated. l)ependin,g on the 
depth of the tla.gstone the bed 
is then filled in with pebbles, 
rocks, old cement, broken bricks 
etc., to a deptli nowhere less 
than 8 inches, and in the center 
proportionately higher. Next a 
covering of sand and gravel to 
fill in the spaces. Finish with a 
good cactus plantin.g soil and af¬ 
ter plants are in place cover 
thickly with gravel and rough 
worn rocks a.^ they will prevent 
washing from rains and .give the 
real desert finish and atmosphere. 
Watering of rock gardens should be decreased in 
late summer so that plants will begin the winter 
liartially shrunken and in saft' condition to with- 
."tand cold and moisture. If too plump and succulent 
they are liable to frost rupture. Rock gardens should 
be planted in spring and summer to give plants time 
to reroot. 
EUPHORBIAS 
Euphorbias are not cacti, but are propagated under 
similar conditions. They have fleshy stems, are 
some times quite thorny, are mostly leafless in 
character, making them natural companion pkints 
to cactus. Insects do not trouble them, and as they 
grow rapidly they are ver>' satisfactory members of 
any collection. 
We have for collectors—E. lactea, E. grandicomis, 
E. tirucalli, E. pseudocactus, E. canariensis, E. 
tithymalus, E. mitriformis, E. obesa, E. splendens 
and others.
