118 NATURE STUDY AND AGRICULTURE 
The Hydrangea when in bloom is one of the most conspicu- 
ous shrubs to be found. It bears immense clusters of white 
flowers and is successful in all but the driest and coldest parts 
of the Northwest. There are several good varieties. 
The Lilac is one of our most valuable shrubs and is found 
wherever there is any attempt made in ornamental planting. 
It has attractive foliage and a wealth of very fragrant flowers.

There are several distinct species and almost innumerable 
varieties, of which we can mention only three. (1) The 
common purple lilac is the most extensively used of all and 
needs no description here. (2) The common white lilac is 
similar to the preceding, but has pure white flowers and larger 
and coarser stems. Its bloom is not so abundant. (3) The 
Persian lilac is a smaller and more graceful bush, with more 
slender stems, narrower leaves, and somewhat paler flowers.
