It was a great success from 
the first. The solid masses of 
low growing rock plants form¬ 
ing masses of bloom were a 
great surprise and entirely 
strange to most people of this 
region, and they came by auto¬ 
mobile, and on foot to drink 
in the beauty and to exclaim. 
The near by perennial garden 
where groups of related plants 
are grown in plots, and the 
formal garden of bedding plants 
are likewise admired. 
These three gardens are a 
valuable object lesson. They show

crops are the dominant thought,

kept in bloom through blazing 
sun of the bravest season. 
One does not need to depend 
entirely on the nurseryman for 
garden materials. There are 
native flowers of rare and deli¬ 
cate beauty, some of which are 
nearing extinction through 
competition with agriculture. 
Among these are the Camassia 
and the Shooting-star, plants 
worthy of a place in any gar¬ 
den. 
People from the country and 
from other towns come to see 
these three gardens and it would 
seem that many must have 
carried the pictures with them 
and been stimulated to the point of adding at least a few new 
flowers to their own door-yards. 
A MOST EASILY GROWN THREE DOZEN 
MONTAGUE FREE 
Horticulturist, Brooklyn Botanic Garden 
Editors’ Note: In a recent lecture on “ Rock Gardens In America'' before the Horticultural Society of New York, Mr. Free recommended the following thirty- 
six as a most amenable and easily grown group of plants and one likely to give the amateur considerable satisfaction without undue fussing. Mr. Free’s selection is 
the result of extended experimentation with alpines and other plants in the rockery at the Brooklyn Botanic Garden—a rockery, by the way, formed entirely of 
glaciated boulders found in the neighborhood and as such carrying a practical suggestion for gardeners in the regions where similar boulders abound—
