HARDY HERBACEOUS AND ROCK-PLANTS 
Pulmonaria angustifolia azurea. See page 71 
PYRETHRUM (Chrysanthemum coccineum). 3 10 100 
The Pyrethrums are so closely related to 
the hardy Chrysanthemums that they are 
frequently called “Spring-flowering Chrys¬ 
anthemums.” They are extremely popu¬ 
lar in Europe where the hybrid varieties 
run into the hundreds, and they are gaining 
new admirers in this country each season. 
For cut-flower decoration they are very 
desirable, lasting longer in water than most 
of the other flowers. The colors range from 
snow-white to darkest crimson.
