14 THE GREEN THUMB 
the writer has tried out have so far 
been somewhat of an anti-climax after 
the French lilac show. 
The species pubescens so_ highly 
rated for its fragrance by eastern 
writers opens its buds so early in Den- 
ver that frequently it is ruined or badly 
damaged by frost. The fragrance of 
the few inconspicuous blossoms of 
pubescens that occasionally survive 
late winter and early spring freezes is 
very different from that of the com- 
mon lilac. 
Mrs. Marriage and Mr. Bechtold 
each seem to have had some degree of 

success with the species tomentella, 
but the writer’s experience was that 
tomentella winter killed to the ground 
every year in Denver. 
With the exceptions of the species 
pubescens and tomentella and Lake’s 
adverse report on the hybrid chinensis 
alba at Gunnison, (chinensis alba re- 
ported as growing well in Denver), no 
other species or hybrids were reported 
as not liking our Colorado climate. 
The following is a tabulation of the 
Colorado survey on the species other 
than Syringa vulgaris and its modern 
named varieties:
