ROCK PLANTS 
R OCK GARDENS harmonize with our New England landscape with its 
outcropping ledges and rambling stone walls. They require little space and 
a secluded corner is available in almost every yard. They form a setting for 
many of our frail native plants and small herbaceous plants of creeping habit not 
suited to the perennial border. The green of dwarf evergreens, the varied tones of 
plant foliage, and the colors of flowers are delightful with the gray surfaces of 
stones. The choice of rocks, and the placing of them with regard to conserving 
moisture and forming pockets for plant roots, and with care for natural effect, is 
an art requiring thought and patience. Help can be gained by observation of rocks 
in natural scenery, and by consulting books on rock gardens. 
The following plants are suitable for small rock gardens. Descriptions and prices 
are given in the other sections of the catalogue. Many of the smaller varieties of 
bulbs, like Muscari and Scilla, which we offer in the fall, are charming additions.
