ROCK-GARDEN PLANTS and Collection 
T HE growing of alpine plants is probably the most highly specialized form of outdoor gardening. It is a fascinating 
pastime because of the intrinsic beauty of the miniature perennials as well as the real difficulties encountered in making 
them happy away from their mountain homes. The wise gardener will not be in too much of a hurry to assemble an 
expensive collection of tricky alpines. He will proceed more slowly, developing the broad outlines of his garden and furnish¬ 
ing it, as it were, with plants which are easy to grow and are known to be adapted to his local conditions. In the friendly 
setting provided by such congenial plants he may then venture into the more esthetic grounds of the high alpines. 
In the list on this page we have tried to gather together varieties of genuine rock-garden merit, the kind of thing that 
everybody depends on for the broad, general, well-furnished garden-effect, and which can be depended on to thrive year 
after year without too much bothersome care. Here are low, mat-forming plants which may be allowed to drape themselves 
over difficult rock-joints or to cover level patches and cracks between stepping-stones. There are some trailers which will 
droop artistically over large boulders or run along the edge of a curbing, and may at times be useful for covering bare spots 
where earlier blooming plants may have disappeared. There are also interesting little tufted plants for tucking into the 
protected corners or placing at points where minor accent effects are needed. 
The point is that these are all dependable plants. They are true citizens of the rock-garden and belong there. Such a 
collection as this is bound to make a fine effect in a brand-new rockery whether anything else is planted or not, and they 
are indispensable to the good appearance of older collections.
