Recently we visited the garden of one of our customers who had 
phoned us to come and see her L. auratum which were “eight feet tall 
growing up into the apple tree.” This garden is a very simple illus- 
tration of the success possible through thoughtful planning. The 
whole area is rather small; it is well broken by light shrubbery and 
perennials; and in the same garden are Madonnas and speciosum mag- 
nificum both infected with mosaic, less than twenty feet from Regals, 
Tigers and auratum which are clean and have remained clean in this 
supposedly dangerous company for the last five years. ; 
For the gardener’s convenience we are classifying the more im- 
portant varieties according to their susceptibility to mosaic: 
Group I 
The first group consists of a number of: fine standard garden 
lilies which always have mosaic. One or two have had it for hundreds 
of years. In spite of this they are all splendid plants that delight 
their owners year after year. 
L. candidum L. chalcedonicum (with rare exceptions) 
L. elegans L. princeps, George C. Creelman 
L. testaceum L. T. A. Havemeyer 
L. umbellatum L. tigrinum (with rare exceptions) 
Group IT 
The second group, at the other extreme as to susceptibility, 
consists of those lilies that resist infection to the point where they 
can be safely considered immune. 
L. Brownli (type) L. Martagon (all forms) 
L. giganteum himaliacum L. pardalinum (all forms) 
L. Hansonii The Martagon-Hansonii hybrids 
Group I 
The third group is lable to infection but does not acquire it 
readily and tends to survive for a number of years in the garden, 
though the plants will gradually deteriorate somewhat and may finally 
die out.1 
L. regale L. Maxwill! 
L. tenuifolium L. sulphureum1 
L. Willmottiaet L. monadelphum Szovitzianum1 
L. Henryit All of the Preston, Stooke’s and 
L. cernuum Bellingham hybrids! 
Group IV 
The fourth group consists of those lilies that are most highly 
susceptible to infection and rarely survive more than a single season 
when infected. 
L. auratum L. japonicum 
L. canadensel L. superbum1 
L. formosanum 
These classifications while an invaluable guide to the gardener 
are somewhat artificial. Actually the two hundred odd varieties and 
species of lilies run the whole gamut from susceptibility to immunity 
and within each classification there is considerable range in regard to 
1 Those designated are less susceptible than the others within the 
given group. Also, individual plants within Groups III and IV may 
prove relatively resistant.
