BLUE AND PURPLE FLOWERS 
Heart-leaved Aster {Aster cordifoUus) . August to 
December. 
A species averaging two or three feet high, noticeable for the 
resemblance of its flower-cluster in form and color to that of 
the common lilac. The flowers are not quite as large as a ten- 
cent piece. The leaves are heart-shaped, with stalks. Very 
common along woody roadsides and in open woods. 
Stiff Aster. Linear-leaved Aster (Aster Unariif alius). 
Late July to October. 
A common low aster with maximum height of two feet, 
growing in sandy soil by the roadsides, having a short, stiff stem. 
Its straight and narrow, rough and shiny leaves somewhat sug- 
gest the foliage of the fir. The light-purple or violet flowers 
are about the size of a quarter and grow separately on the ends 
of branches. 
Large-leaved Aster (Aster macrophyllus) . August, 
September. 
A plant of the open woods, with stout stem which rises from 
a clump of large, heart-shaped leaves, each upon a long, slender 
stalk. The flowers, about the size of a quarter, vary from lilac 
to whitish, and average from twelve to fifteen rays. The upper 
leaves are without stalks, the lower heart-shaped with long 
stalks, the others with broadly winged stalks; all toothed.
