A WORD TO THE READER 
N the following classification I do not offer an ex- 
haustive list of hardy trees, shrubs, perennials or 
annuals. Many are omitted that are choice, but 
=4 not quite hardy beyond the latitude of New York 
City; also very expensive varieties are not included among 
shrubs. I name those that I have actually grown, or am now 
experimenting with. The nomenclature has been derived 
from Nicholson’s “Illustrated Dictionary of Gardening,” 
Asa Gray’s “Field, Forest and Garden,” R. G. Leavitt’s 
“Outlines of Botany,” and Mrs. Loudon’s “Gardening for 
Ladies.” 
In making color divisions, I have given “White Flowers” 
the first place, because the majority of plants have one or 
more white varieties. The cultural directions for those 
grouped under “White Flowers” will not be repeated in other 
lists, even though their names may appear, duly recorded as 
special varieties, under other color lists. Should a plant have 
no worthy white variety and appear for the first time under 
“Blue” or other color, the cultural directions will accompany 
its first mention, to which the reader will be referred for the 
culture of subsequent varieties, that may occur in later color 
lists; and so on throughout the whole Appendix. 
I have arranged this very simple, though seemingly com- 
plex, classification, which catalogues each plant separately 
throughout the different lists just as far as it has representa- 
tives of pure color, in order to give amateurs every oppor-
