DWARF TREES." 
ALPINES AND ROCK PLANTS 
1952

This list is an answer to thousandg of requests following our major exhi- 
bitions in Washington, D. C., Baltimore, Maryland, Philadelphia, Pennsylvania 
and especially, at the New England Spring Flower Show in _ Boston, 
Massachusetts. 
Although it is far from complete, it contains the plants that have won 
for us since 1933, twenty-two gold medals, the President’s Cup both in 1944 
and 1952, the Totty Memorial Medal, the coveted Burrage Gold Vase, which 
was awarded to the most outstanding of all exhibits in 1948, and on four 
occasions, the gold medal of the Horticultural Society of New York for the 
most beautiful exhibit in the Show. 
Many of these plants will prove extremely hardy -- withstanding low 
temperatures and prolonged periods of drought. They require a porous 
soil. A rich garden loam will need one-third sand and gravel spaded into it 
and thoroughly mixed. It will be necessary to follow the key as to sun or 
shade. A sun-loving plant will grow tall and weak in shade; in reverse, a 
shade plant will lose its rich foliage in the sun. Rock plants have two enemies. 
Rich, sticky loam, which will insure their death in one or two seasons, and 
weeds, especially perennial weeds, such as, witchgrass, sorrel, and others 
Be sure to clean the ground thoroughly. 
Adhering to these simple rules, these plants will surprise you and be a 
never ending source of pleasure for little money. 
The blossoming dates are, of course, as we find them and pertain to the 
vicinity of Boston. Further North the blossoming date would be later; in the 
South it would be earlier. Also, from year to year, there is a slight variation 
in the blossoming date due to temperature changes; for example, an unsea- Lr 
sonably hot Spring will move all dates up a week or so. os
