fall and keep the grass and weeds from choking out the 

 plants daring the summer. 



HARDY FEVERFEW (Pyrethrum roseum and cinerari- 

 folium). Many beautiful double-flowering varieties of the 

 above species have been introduced and are so easily grown 

 and beautiful both in foliage and flower that they should 

 be more generally planted. The blossoms of these species 

 are used for the manufacture of the powder known under 

 the names of Persian, Dalmatian, and Buhack insect- 

 powder. 



BLOODROOT (Sanguinaria Canadensis). A very com- 

 mon and most beautiful native plant, producing its pure 

 white flowers very early in the spring. It grows best in 

 moist, shaded places among rocks and underbrush, and is 

 easily transplanted from its wild state to the garden. The 

 very early blossoms are followed by broad, lobed glaucous 

 leaves that retain their beauty for a considerable part of 

 the summer.
