MISSOURI BOTANICAL GARDEN BULLETIN ive 
the walks and added a finish to the display which it has not 
heretofore been possible to obtain. For this manner of cul- 
tivation the varieties with pendant growth were selected, those 
best adapted being ‘‘ Anna,’’ a single white, ‘‘Cosmos,’’ single 
pink, and a single yellow somewhat suggesting C. indicum. 
The plants were grown in the baskets from the cutting, or 
early rooting, stage, in April, to the flowering period. 
The largest November attendance, excluding the World’s 
Fair period, was recorded while this show was on, the total 
for the month being over 93,000. The maximum Sunday at- 
tendanee was recorded on November 21, when 18,000 people 
passed through the floral display house between 1 and 5 
P. M. The line of visitors was continuous from the flower 
house to the east end of the rose garden. 
The show was discontinued November 30, and the flowers 
were distributed to the hospitals through the Book and Flower 
Guild. The total number of flowers given away amounted to 
over 40,000. Over twenty-five local hospitals received flowers, 
the City Hospital receiving the maximum of 7,000. 
NATIVE PLANTS SUITABLE FOR THE GARDENS OF 
MISSOURI AND ADJOINING STATES 
XIII. NATIVE TREES AND SHRUBS FOR UNFAVORABLE AND 
SMOKY CITY CONDITIONS 
The smoky atmosphere of manufacturing cities, such as St. 
Louis, is very injurious to trees and shrubs. Many species 
will not stand these conditions at all, particularly the conifers 
and other evergreen plants which do not discard their leaves 
annually. 
Among the conifers the pines will survive longer 
than others, and among the _ broad-leaved evergreen 
trees, the holly, Zlex opaca, will grow quite well in moderately 
smoky conditions. Conifers are, however, not recommended 
to be planted extensively in manufacturing cities where bitu- 
minous coal is used as fuel. Fortunately some deciduous trees 
and shrubs will thrive in a smoky atmosphere, as indicated by 
the following list of native material:
