among the easiest of all rock garden subjects, 
many of the very finest of them will show such 
a wonderful appreciation of a little special atten¬ 
tion in the way of shade, moisture, soil and sea¬ 
sonal temperatures, that any one who loves them 
will be glad to meet their simple requirements 
if they know just what these requirements are. 
So we are grouping the varieties according to their 
special needs, which if observed will be a lot of 
help to those unfamiliar with the many rare and 
less common sorts. It may save losses and add to 
the satisfaction of growing this most versatile 
genus of rock plants. ; . 
GROUP A 
The following group will be happy in average 
garden conditions, north or south. Many if not all 
will appreciate a little shade at mid day where 
ever the summers are very hot and dry. On the 
whole a selection from this group will prove sat¬ 
isfactory in almost any part of the U. S. A.

This group will require cool, partly shady situa¬

may prove fatal.
