ROCK GARDEN PLANTS 
This form of a flower garden is increasing in popu¬ 
larity by leaps and bounds. 
It is not necessary to own a large estate to have a 
rockery or rock garden, as they can be built to fit the 
small home grounds as well, proper consideration 
being given to the location. The best site is on sloping 
ground where there is good drainage but with a little 
care they can be built on the level or any place avail¬ 
able. A sunny situation is best as most rock plants are 
sun loving.
